ABSTRACT:
A voltage comparator where the difference of currents from transistors is converted into voltage, which is amplified and conducted to a gate terminal of a switching transistor. A source of a limiting transistor is connected to the gate terminal. The voltage at the gate terminal when the switching transistor is quiescent is equal to a value between eight and nine tenths of the switching voltage at the gate of the transistor, at which voltage the transistor triggers a switching in the output stage. A response to an input voltage change at one direction of the sign reversal of the difference of the input voltages is fast. The voltage comparator is robust and reliable with regard to temperature variations.
