摘要： Certain aspects of the present disclosure generally relate to a differential amplifier implemented using a complementary metal-oxide-semiconductor (CMOS) structure. The differential amplifier generally includes a first pair of transistors and a second pair of transistors coupled to the first pair of transistors. The gates of the first pair of transistors and gates of the second pair of transistors may be coupled to respective differential input nodes of the differential amplifier, and drains of the first pair of transistors and drains of the second pair of transistors may be coupled to respective differential output nodes of the differential amplifier. In certain aspects, the differential amplifier may include a biasing transistor having a drain coupled to a source of a transistor of the first pair of transistors and having a gate coupled to a common-mode feedback (CMFB) path of the differential amplifier.
