Abstract
In the voltage controlled oscillator disclosed herein, the charging and discharging of a timing capacitor is controlled by a differential input comparator which establishes precisely defined switching thresholds. The comparator input circuit is provided with an internally generated, temperature compensated input bias current which substantially relieves the timing components from providing bias current, thereby facilitating a wide range of operation.
