Abstract
A high speed rectangle function generator which provides a rectangular out voltage in response to an input voltage. A voltage divider produces switching points in conjunction with an input voltage to switch inversion and non-inversion amplifiers. The outputs of the inversion and non-inversion amplifiers are summed to produce a rectangular output voltage. Operational amplifiers are utilized as inversion and non-inversion amplifiers.
Claims12
A high speed rectangle function generator for generating an output voltage which is a rectangle function of a varying input voltage, comprising:
- a plurality of amplifiers for generating amplifier output voltages which are switched between two voltage levels in accordance with the varying input voltage and respective fixed voltages, each amplifier output voltage being switched at high speed to one voltage level whenever the input voltage rises above the fixed voltage and being switched at high speed to the other voltage level whenever the input voltage falls below the fixed voltage;
- fixed voltage generating means for generating said fixed voltages which are supplied respectively to said amplifiers;
- and
- summing means for summing the amplifier output voltages to generate the output voltage of the rectangle function generator;
- wherein the amplifiers are connected to receive the input voltage and the respective fixed voltages and to supply the amplifier output voltages to the summing means as alternately arranged inversion and non-inversion amplifiers so that, in each pair of amplifiers receiving adjacent fixed voltages, one amplifier is connected as an inversion amplifier and the other amplifier is connected as a non-inversion amplifier.
