Abstract
A high-speed differential comparator (300) is disclosed. A transconductance device is connected to the input terminal and the first and second output terminals (305 and 309, respectively) of the comparator. The transconductance device receives an input voltage (V.sub.IN) from the input terminal and generates a current between the first and second output terminals (305 and 309) in response to the input voltage. A load is connected between the first and second output terminals. The load, which includes a resonant tunneling diode (313), conducts the current and generates a voltage difference between the first and second output terminals (305 and 309) in response to the current. The comparator responds to input voltages at high speed and may be used for high frequency signal sampling and level determination.
