ABSTRACT:
An exponential sweep multivibrator capable of extremely high-speed operation and producing an exponential output waveform. This multivibrator in addition to incorporating within the circuitry thereof a "digital" device such as a NAND gate, integrates the collector current from a controlled source transistor in a capacitor. The collector current is proportional to the output voltage of the digital gate, which in turn is proportional to the sum of the input current and a current derived from the output voltage of the multivibrator. As a result thereof an output waveshape is produced whose rate of increase is proportional to its instantaneous amplitude, which, by definition, is an exponential function of time.
