12 Differential Amplifier with active load using PDM | Cadence | gpdk180 | Simulation | Tutorial

This simulation shows the working of a differential amplifier. The yellow and green waveforms are the two input signals applied to the circuit, and the violet waveform is the output. The amplifier responds to the difference between the two inputs, rejecting the common part and amplifying only the variation between them. As seen in the graph, the output (violet) is a scaled version of the difference of the two input signals, which is the key feature of a differential amplifier used in signal cond
