英文摘要：

Aiming at various application interface circuits of MEMS thermal sensors, high performance preamplifiers is designed. The concept of setting up IP library of pre-amplifiers for CMOS-process-compatible MEMS thermal sensors is proposed. By extracting related devices typical parameters, pre-amplifiers which is low-power, low-noise and meet special requirements such as precision and speed are designed. Three different structures of amplifiers are analyzed based on CSMC 0.5 μm CMOS standard process library are designed and simulated by Cadence software. Simulation results show that three different structures amplifier can be used in MEMS thermal sensors for relevant performance requirements.
