The circuit is a simple transimpedance amplifier that converts the device under test’s (DUT’s) IDS into an output voltage (Fig. 1). O p-amp U1A maintains the DUT’s source voltage at 0 V.

The actual circuit of the generator is built with three LM386 ICs. It produces two frequencies, selectable via double-pole double-throw (DPDT) switch S1 (Fig. 2).

A cubic function generator is an essential component in TCXOs to compensate for the frequency variation of quartz resonators during temperature change. The authors present a fully analog CMOS cubic ...
