The Vertical Slit-based Field-Effect Transistor (VeSFET) is a novel junctionless device with two identical, independently controlled gates. The VeSFET, so far prototyped only as single-device test structures, has been considered in the literature exclusively as a component of digital systems. This paper 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.
