ABSTRACT:
An astable multivibrator comprising a capacitor connected between a first output signal and a third output signal, an amplification circuit connected between the first and third output signals, a delay for delaying a signal logic-converted from the first output signal and for outputting a second output signal, and a variable resistor connected between the first output signal and an output node of the delay. High frequency oscillation performance is enhanced and a larger voltage operating range is obtained by excluding the effect of feedback current.
