UNIVERSAL TIME-PULSE INTEGRATING VOLTAGE CONVERTER WITH PULSE-WIDTH MODULATION FUNCTION Russian patent published in 2024 - IPC H03K3/13 

FIELD: precision pulse electronics.

SUBSTANCE: disclosed is a time-pulse integrating voltage converter with a pulse-width modulation function, consisting of four operational amplifiers, on which two voltage repeaters, an integrator and a comparator are implemented, four-channel switch and three inputs, through which two input voltages are connected and an electric jumper may or may not be connected. Four-channel switch is connected to the first input and output of the inverting repeater of the first input voltage and to the second input and output of the inverting repeater of the second input voltage in the input circuits of the comparator and integrator, respectively.

EFFECT: considerable increase in the operating range of variation of input voltages, in which the required linearity of conversion functions, low conversion error, reduced time for adjusting the converter circuit are achieved.
