Micropower VCO (Voltage-Controlled Oscillator)

This is a schematic diagram of a micropower voltage-controlled oscillator circuit. This circuit can generate square and triangle wave outputs and only need 50µA from a single 5 V supply. This circuit consist of combination of an  inexpensive quad CMOS switch and two OP90s. Here is schematic diagram of the  the circuit : The integrator in this circuit is A1. […]
