A process insensitive NMOS operational amplifier

Abstract: New York, NY AN OPERATIONAL AMPLIFIER which uses an enhancement/ depletion NMOS technology has been designed for low power Consumption, low process sensitivity, large bandwidth and small area.The circuit, shown in Figure 1, features a self-biased input stage that eliminates the need for precise matching between the depletion loads M3A and M3B and the tail current source hl5. This is achieved in the following manner: h42A and M2B have one-half the width of M I A and ht1B and thus their combined current is eq… Show more

“…Process variation in the form of variation can be compensated by using a number of circuit techniques such as adding a tuning sub-circuit [13]. Since the design and fabrication of SiC JFET based circuits are in an early stage, the aim of this paper is to avoid complexity and employ a minimum number of transistors.…”

“…The fabrication technology for SiC devices and more specifically SiC JFET transistors and differential pairs is still evolving; therefore, the design should accommodate the currently larger tolerances for devices. The small signal differential gain equation of the diffamp is presented in (13) and (14):…”
