Abstract
A biasing circuit biases the second of two input terminals of a differential amplifier at a first reference level. A sawtooth voltage of a first frequency is coupled to the first input terminal. A bilevel voltage generated at an output terminal of the differential amplifier shifts levels when the sawtooth voltage equals the first reference voltage level. A second biasing circuit coupled to the first input terminal biases the first input terminal at a second reference voltage level differing from the first reference level by an offset voltage. The second reference level is selected to equalize the duration of each of the bilevel voltages. Output signals are produced when the bilevel voltage shifts levels, thereby producing the output signals at twice the first frequency.
