This sawtooth generator circuit use 741 IC and is used as a musical sound synthesizer. The sawtooth input signal is continously changed through P2 to a waveform with a doubled frequency and half ...
This sawtooth-oscillator circuit,drawing less than 3.2 µA andworking at under 1V, is a useful buildingblock that fits the bill for extremelylow-power consumption and operationto low supply voltages.
