Amplifier Simulation and Test-Benches
In this discussion, we aim to explore two fundamental aspects that are often overlooked in textbooks. Firstly, we’ll delve into how to determine reasonable specifications for your amplifier. Secondly, we’ll examine how to thoroughly verify the performance of such an amplifier. If an amplifier is required somewhere in your system, such as in a filter…

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…
