Frequency of square and triangle outputs can be ad justed over range of 1,000,000:1 with 10K pot or by varying DC voltage applied to pin 5 of CA3080A over wire line from remote location. CA3140 serves as noninverting readout amplifier for triangle wave developed across integrating capacitor network at output of CA3080A current source. Second CA3080 acts as high-hysteresis switch having trip level established by four diodes,to give desired square-wave output．－''Linear Integrated Circuits and MOS/FET's,''RCA Solid State Divsion,Somerville,NJ,1977,p 248－254.
