The Miller-OTA amplifier is widely used in CMOS technology and is sufficient for many applications. If your gain requirements are within ±70 to 80 dB, your load is reasonable (preferably only capacitive), and you require only a single-ended output, the Miller-OTA is a good choice. Its simplicity, straightforward biasing, and wide output range make it…

A common application of simple current mirrors is in single stage amplifiers with an active load. This common-source configuration (see Fig. 1) is highly favored as a gain stage, especially when high input impedance is desired. The term “common source” refers to the common node between the input and output voltages, which is the source…

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…
