Small-Signal Parameters of the VeSFET and Its Application in Analog Circuits
Dominik Krzysztof Kasprowicz , Bartosz Swacha
AbstractThe Vertical Slit-based Field-Effect Transistor (VeSFET) is a novel junctionless device with two identical, independently controlled gates. The VeSFET, so fa prototyped only as single-device test structures, has been considered in the literaturę exclusively as a component of digital systems. This article shows that the device’s properties make it attractive also for the analog designer. Some of the VeSFET’s analog-design related parameters are compared with those of the MOSFET of the corresponding technology node. Subsequently, a two-stage Miller operational transconductance amplifier (OTA) is proposed that makes use of the VeSFET’s two independently-controlled gates to drastically reduce the common-mode gain. An example application of the OTA in a current mirror is also presented.
