PMOS transistors are less vulnerable to substrate noise since they’re placed in separate wells; designers implement guard rings to attenuate the substrate noise propagation. However, substrate noise ...
To design a 2-stage, single-ended op-amp with PMOS inputs with the following design specifications. The first stage is a differential pair with a current mirror load. The second stage is a common ...
Many single-supply operational amplifiers are capable of rail-to-rail input operation, if they have the proper input circuitry to support this function. This article is an expansion of the blog post ...
