CMOS amplifier circuit which minimizes power supply noise coupled via a substrate |
摘要 |
A CMOS circuit having a differential input stage which provides a single output is provided. An output stage has a capacitor which is used as a Miller integrator coupled thereto for frequency stabilization. A cascode portion is coupled to the Miller integrator to maintain one of the capacitor's electrodes at a predetermined voltage potential. A compensation portion is coupled to the cascode portion to compensate for power supply induced errors created when either an N-channel transistor in an N-well process or a P-channel transistor in a P-well process is used in the cascode portion.
