Found in a 1968 American documentation, this circuit generates sawtooth signals whose rise and fall times are determined by C1 and C2. Transistors support modern equivalents.
This is yet another version of the light-controlled oscillator that can be found on this website. This...
This filter operates in the “opposite” way to the previous one (CIR8814), cutting all signals...
This circuit is from a 1957 Japanese magazine, showing the use of OC19 in a high voltage inverter. The...
