This is a quartz-stabilized oscillator circuit with electronic gain control. Replacing the common filament lamp  for amplitude stabilization, this circuit use an electronic gain control inside the stabilization loop. A 50-Ω variable resistor should be trimmed until the output level show 2-Vpp magnitude oscillations op-amp A1 output. Here is  the schematic diagram of the circuit: [Circuit’s schematic diagram source: Linear […]

This is an astable multivibrator  (oscillator) circuit using CMOS inverter. This circuit uses CD4007 or MC14007. This circuit has operating frequency range of 10kHz to 10MHz.  The frequency is not determined only by the crystal, but fine tuned further by C and R that determines the exact operating frequency of this circuit. For proper operation, Pin 1 and 5 should […]
