Figure shows a MOSFET diff-amp with an active load. Transistors M1 and M2 are n-channel devices and form the differential pair biased with Iq. The load circuit consists of transistors M3, and M4, both p-channel devices, connected in a current mirror configuration. A one-sided output is taken from the common …
