N2 - Si-gated field emitter arrays (Si-GFEAs) are strong candidates for nano vacuum channel transistors (NVCTs). In this work, Si-GFEA die with 1000 X1000 arrays were used to create a Colpitts oscillator circuit. First, transfer and output characteristics sweeps were carried and based on those data, a LTSpice vacuum transistor (VT) model was developed. Then the model was used to develop a Colpitts oscillator circuit. The circuit was experimentally tested where the collector voltage was kept at 200 V DC and the gate voltage was kept at 50V DC. From the experiment, an oscillation frequency of 152 kHz was observed with a maximum amplitude of of Vpp=4.38 V.
