Simple Differential Pair Amplifier
Besides current mirrors and basic amplification stages like common-source, common-gate, and source-follower amplifiers, the differential pair is considered one of the most important circuit blocks in analog design. Unlike basic amplifier stages, the differential stage has two signal inputs of opposite signs, allowing it to amplify a differential input signal, which is a tremendous advantage…

Constant-\(g_m\) Biasing Circuit
The schematic of the constant-\(g_m\) bias circuit is shown in Fig. 1. It consists of two cross-coupled current mirrors, where one of the source contacts, e.g. of an NMOS transistor, is degenerated by a source resistor. This results in a unique operating point of the circuit other than zero current, which defines the pass current…
