Open the CIPO recordAbstract From the Canadian patent
A pulse duration to current converter wherein the output current is proportional to the duty cycle or duration, of, the input pulse. A first current source is modulated by an input signal while a second current source is held constant by an input reference signal level. The sum of the currents from the first and second current sources are averaged by a filter network to produce an output signal that is subsequently applied to the noninverting input of an amplifier to be amplified thereby. An output signal from the amplifier is converted to a current output by an output circuit driven by the amplifier. The output circuit will operate with maximum load impedances by using a level shifter at …
