ABSTRACT:
A continuous time common mode feedback amplifier CTCMFB (300) is suitable for applications requiring fully differential amplifiers in low voltage supply requirements. Two mirror image, low gain CMOS amplifiers (MP0/MP2 and MP3/MP4) in the CTCMFB (300) define and stabilize the common mode output voltage, Vcm, of the main differential amplifier (102). The transient response of the common mode amplifier (300) can be adjusted independently of the transient response of the main differential amplifier (102), allowing fast transient response to the main differential amplifier.
