RS Flip-Flop Using OP-AMP

This RS flip-flop is op-amp version of classic flip-flop which uses two inverting amplifier. The non-iverting input is floating, and we can assume that the voltage level of this floating pin is between VCC and ground, while the outputs will always be high or low. The high level of the output will be 1-2 volts …

Analog Multiplier-Divider with 4136 Op-Amps

This unique circuit below can be used as divider and multiplier. This circuit is formed by all four sections of a 4136 . The Q1 through Q4 can be any PNP transistor, but that must matched transistors. The transistor matching determine the acurracy of the divider and multiplier circuit. Here is the schematic diagram of …
