Among them, the operational amplifier Al is integral circuit, and operational amplifier A2 is the comparator circuit; transistor VTl for the discharge circuit. In the circuit, VT1 and VT2 use 2SC495, and VT3 uses 2SAlO15, operational amplifiers Al and A2 use TA75458. Output frequency fo ≈ Ui / (RlClU2), where, U2 is the regulator VDz is regulated voltage.
