Abstract Germanium (Ge) tunnel field effect transistor (TFET) is considered to be an excellent solution to resolve the low on-currents issue of Silicon-based TFETs. Whereas, process variability in any low technology node devices (sub-100 nm) is a crucial subject of matter which affects the device reliability and dependability in advanced SoC applications. In this brief, we have investigated the two main process induced variability a) the thickness of the germanium body b) the thickness of gate oxide in Ge-pTFET using Sentaurus TCAD device simulation. The analysis is performed in complete analog domain along with the study of intrinsic RF performance parameters using small signal equivalent model with non-quasi static effect of the device under consideration. The process induced variability is estimated on the figure of merits (FOMs) such as drain current (Ids), transconductance (gm), output resistance (Ro), intrinsic gain (gmRo), unity-gain cutoff frequency (fT), transit frequency of maximum available power gain (fMAX), transport delay (τm), intrinsic resistance (Rgd) and intrinsic capacitances (Cgs, Cgd).
