SWITCH AMPLIFIER WITH STEP VOLTAGE GENERATOR Russian patent published in 1994 - IPC

FIELD: radio transmitting devices. SUBSTANCE: device has multilevel comparator, step voltage generator and additional switch amplifier which outputs positive voltage. New feature is that input of multilevel comparator is connected to output of adder which first input receives amplifying signal and second input is connected to negative bias supply. Coupling is made by additional switch amplifier. This results in correction of positive and negative deviations of output voltage from shape of amplifying signal. EFFECT: decreased non-linear distortion. 3 dwg
