SINGLE_CONTROL_FUNCTION_GENERATOR

Published:2009/7/7 6:42:00 Author:May | From:SeekIC

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.
