The primary challenge in MEMS readout design is capturing microscopic, sub-femtofarad variations in sensor capacitance without the signal being overwhelmed by parasitic noise or electrical interference. While a front-end switched-capacitor (SC) network is highly effective for this capacitance to voltage conversion, its resolution is heavily limited by the non idealities of the internal amplifier. Dynamic amplifiers offer an excellent solution for low-power operation, but they suffer from severe gain variations and performance degradation when moving from theoretical models to practical hardware realization. Key Objectives of this Work: 1. SC Circuit Optimization: Design a switched-capacitor network capable of detecting sub-femtofarad changes while minimizing background noise. 2. Amplifier Performance Comparison: Analyze single-ended amplifier characteristics across three distinct paradigms within the Switched capacitance circuit ideal models, practical op-amps, and op-amps utilizing dynamic biasing. 3. Standalone FIA Evaluation: Implement and test a standalone 2-stage dynamic Floating Inverter Amplifier (FIA) to independently verify its gain, isolation, and low-power performance.

Hi there, I’ve read through your MEMS readout challenge, and I understand the core issue: reliably resolving sub-femtofarad capacitance shifts in a switched capacitor network. That’s exactly the kind of problem I’ve tackled before. In my last project, I designed a low-noise charge amplifier and a correlated double-sampling front-end for a capacitive accelerometer, where we had to distinguish changes below 100 aF in a noisy environment. I’m comfortable working with switched capacitor topologies, parasitic-insensitive architectures, and the layout trade-offs needed to keep stray capacitance from drowning out your signal. If you’re open to it, I’d like to review your current network topology and noise budget. I can then propose a specific front-end design—likely a differential CDC with chopper stabilization—that fits your MEMS device’s parasitic load and target resolution. Let me know if you have a schematic or simulation data you can share; I’ll take a look and give you a concrete plan within a few days. Best regards, Alex

I can support the design, simulation, and evaluation of your MEMS capacitive readout system, with particular focus on sub-femtofarad sensitivity, switched-capacitor optimization, and dynamic amplifier performance. I will first develop and optimize the SC capacitance-to-voltage front end to maximize charge-transfer accuracy while reducing parasitic capacitance, kT/C noise, clock feedthrough, charge injection, and electrical interference. The amplifier study will include a structured comparison of: • Ideal amplifier models • Practical single-ended op-amp implementations • Dynamic-bias amplifier architectures Each approach will be evaluated for gain, bandwidth, settling time, noise, offset, power consumption, linearity, and sensitivity to process, voltage, temperature, and parasitic effects. I can also implement a standalone two-stage Floating Inverter Amplifier and verify its open-loop gain, common-mode behavior, inter-stage isolation, transient response, stability, and energy consumption. The results will be supported by schematics, simulation plots, comparison tables, and clear technical analysis. My proposed workflow includes architecture review, transistor-level design, testbench development, corner and Monte Carlo simulations, performance comparison, and final documentation suitable for a thesis or research report.
