Abstract
A multivibrator capable of extremely high-speed operation and producing a linear sweep waveform. This multivibrator contains within the circuitry thereof a "digital" device such as a NAND gate being used in a "gated linear" mode of operation, a linear, voltage-to-current converter used to convert the output voltage of the "digital" device into a charging current, a capacitor which integrates the charging current thereby converting an amplitude into a time interval and a voltage-sensitive switch. As a result thereof the mulltivibrator of this invention requires only one voltage supply and the useable sweep output voltage is a very large fraction of the supply voltage.
Claims18
A multivibrator compising a "digital" device having first and second inputs and an output, means electrically connected to said "digital" device for accepting a control voltage and directing said control voltage to said first input of said "digital" device, a feedback circuit electrically connected between said first input and said output of said "digital" device, means electrically connected to said output of said "digital" device for converting said "digital" device output voltage into a current, a capacitor electrically connected to said voltage converting means, a DC source electrically connected to said voltage converting means, and a voltage sensitive switching means electrically connected between said capacitor and said second input of said "digital" device whereby said multivibrator is capable of extremely high-speed operation and producing an exceptionally linear sweep waveform.
