    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…

    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…

    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…
