Phase corrected miller compensation of chopper and nested chopper amplifiers |
摘要 |
A circuit architecture ( 200 ) for implementation of compensation based on Miller capacitors in multi-stage chopped amplifiers includes insertion of an additional chopper ( 206 ) in the compensation feedback ( 118, 120 ) pathway. Such compensation is more area efficient than parallel compensation and allows higher bandwidth in multistage amplifiers. The insertion of a chopper in the Miller capacitance feedback loop provides a means to selectively adjust the phase of the feedback by 180 degrees.
