Abstract:
The conventional method of constructing a gain amplifier is to use resistor feedback networks. However, present CMOS technology provides capacitors that offer substantially better tracking and linearity performance over variations in temperature. Draper Laboratory's High Performance Gyroscope currently employs two single-ended amplifiers configured to work fully differentially. Gain is provided with capacitive feedback, but DC stabilization of the amplifiers, necessary to provide bias to the amplifier and prevent output saturation. is achieved with large, external resistors. In this thesis. a. fully-differential gain amplifier using capacitive feedback is proposed. An integratable, on-chip DC stabilization network is also presented.
