Single-control-function-generator

  
This function generator, with an adjustment range in excess of 1,000,000 to 1, uses a CA3160 BiMOS op amp as a voltage follower, a CA3080 OTA as a high-speed comparator, and a CA3080 as a programmable- current source. Three variable capacitors, C1, C2, and C3 shape the triangular signal between 500 kH and 1 MHz.

Capacitors C4 and C5, and the trimmer potentiometer in series with C5, maintain essentially constant ( ±10%) amplitude to 1 MHz.
