I can develop a clean KiCad 10 SPICE-ready current mirror and charge/discharge simulation stage optimized for accurate low-voltage operation at 2.5V. The design will generate matched positive and negative mirrored currents from your 180–400 µA IREF source using optimized NMOS/PMOS mirror topology. I will ensure the mirrors track within the required ±3% accuracy range across DC and transient sweeps. The schematic will include proper startup biasing, reference routing, and stable switching behavior for reliable simulation results. I have strong experience with analog circuit design, current mirrors, low-voltage biasing, and SPICE-based verification workflows. The KiCad project will include a ready-to-run transient testbench showing capacitor charge/discharge behavior and mirrored current traces. All nodes, transistor sizing, and tuning parameters will be clearly labeled for easy future modification and threshold experimentation. I will use KiCad-compatible default SPICE models where possible and provide any additional model setup instructions if required. The final deliverable will open directly in KiCad without errors and be ready for immediate simulation and iteration.

Hello, I understand you already have the VREF and IREF generation stage working from a 2.5 V supply, and now need a KiCad 10 SPICE-ready schematic that generates matched positive and negative mirror currents for controlled capacitor charge/discharge behavior. The focus is accurate current mirroring across the 180 µA–400 µA range, clean transient switching, rail-to-rail compatibility, and a simulation setup that is stable, simple, and easy to modify later. I can design the current mirror stage using matched NMOS/PMOS topologies optimized for low-voltage 2.5 V operation, including proper biasing, startup handling, and SPICE-compatible models for reliable DC and transient analysis. The deliverable will include a complete .kicad_sch file, ready-to-run SPICE testbench, labeled nodes, parameterized transistor sizing, and capacitor charge/discharge plots showing +I_MIRROR and –I_MIRROR tracking IREF within the required tolerance. I can also integrate your validated rail-to-rail comparator/op-amp model into the switching stage if needed. I’m comfortable working directly within KiCad’s simulation environment and can structure the schematic so future tuning of thresholds, resistor values, capacitor sizes, and transistor geometry is straightforward. Once you share the comparator details and any preferred MOSFET models, I can begin building and validating the simulation quickly. Thanks, Asif

⭐⭐⭐⭐⭐ Hello, This is a very clean and well-defined analog/SPICE task, and it fits my experience with low-voltage current mirrors, precision biasing, and KiCad/ngspice simulation workflows. I can create a compact 2.5 V-compatible topology that: • Generates matched sourcing and sinking mirror currents from your IREF • Maintains ±3% tracking accuracy over the 180–400 µA range • Produces stable linear capacitor charge/discharge behavior • Runs directly inside KiCad 10’s integrated ngspice environment My approach would likely use: • PMOS mirror for sourcing current • NMOS mirror for sinking current • Simple cascode or degeneration options only if accuracy requires it • Rail-to-rail comparator integration for threshold switching • Startup/bias stabilization paths to avoid metastable states in transient sims Deliverables: • Complete .kicad_sch schematic • Ready-to-run ngspice testbench • Parameterized MOSFET sizing for easy tuning • Clearly labeled nodes/signals: IREF +I_MIRROR –I_MIRROR VCAP thresholds/control nodes • Simulation plots demonstrating: current tracking capacitor ramps switching transitions I’ll keep everything compatible with: • KiCad default SPICE models where practical • your validated rail-to-rail op-amp/comparator models • fast transient simulation without unnecessary complexity

Dear Client, The biggest risk in this project is not creating positive and negative current mirrors in KiCad SPICE. It is building a simulation that appears stable at one operating point but becomes inaccurate, nonlinear, or unstable once the current range, capacitor switching, and transient behavior interact in the full circuit. That is where practical analog simulation experience matters. I would approach this by: 1. reviewing the existing VREF/IREF stage and operating conditions to identify risks in MOSFET matching, compliance range, startup behavior, rail limitations, and transient switching accuracy 2. designing a clean current mirror topology optimized for 2.5 V operation with stable charge/discharge behavior, practical device sizing, and simulation-ready SPICE integration inside KiCad 10 3. validating transient and DC sweep performance so the delivered schematic produces repeatable mirrored-current accuracy and clean capacitor charge/discharge waveforms immediately after opening the project ✅ Quick Questions: 1. Which comparator/op-amp model would you like integrated into the simulation environment? 2. What capacitor range are you expecting for the charge/discharge timing tests? Message me and I’ll outline the cleanest first step so this moves toward a stable and tunable simulation platform—not just another schematic that partially works under limited conditions. Best regards, Prat PCB Must Innovations

@ihors29

Hi, Yes, this is well within my scope. I can create a KiCad 10-ready schematic and SPICE testbench that generates matched positive and negative current mirrors from your 180–400 µA IREF source and verifies capacitor charge/discharge behavior. I’ve previously worked on low-voltage analog/SPICE designs involving current mirrors, rail-to-rail operation, comparator-controlled switching, and USB/power mixed-signal systems, including optimization for ngspice convergence and transient stability. Typical turnaround for a project like this is about 2–4 days depending on tuning requirements for matching accuracy and switching behavior. A couple quick questions: - What capacitor range and switching frequency are you targeting? - Should the comparator hysteresis/control logic also be included in the simulation bench? Looking forward to working with you. Thank you, Ihor
