Design Techniques for MOSFET-Only Low-Voltage Fully Differential CMOS Switched-Capacitor Amplifiers
並列摘要
Two 1-V fully differential CMOS switched-capacitor amplifiers in a standard CMOS 0.18μm technology are presented. The circuit uses substrate-biased MOSFETs in depletion region as capacitors linearized by compensation technique. The improved bootstrapped switches are used to allow rail-to-rail signal swing. The circuit design of major building blocks is described. The performance of these two circuits is demonstrated by simulation results. The simulation results confirm the capability of compensated depletion-mode MOS capacitors to fulfill circuit requirements.
