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.

TK shows a Function Generator kitA function generator is an indispensable of electronics lab equipment, but unfortunately such a costly device is not within the easy reach of an average electronics ...

A low-power and low-voltage simple CMOS exponential function generator circuit is proposed. It is based on simple current mirrors able to operate at low supply voltage. The design of the circuit is ...

This circuit generate sine wave oscillation, but actually we can modify the circuit to generate triangle or square wave function. This waveform generator integrated circuit chip is very interesting ...

Our modification to the function-generator circuit allows low-voltage battery operation (Fig. 2). Current mirrors—Q1-R3, Q2-R4, Q3-R5, and Q4-R6—replace the resistors.
