Abstract
A negative resistance generator is disclosed herein. The negative resistance generator includes a first signal end for receiving a first signal which includes first AC/DC components, a second signal end for receiving a second signal which includes second AC/DC components, first and second transistors, a power source circuit, a first and a second DC level setting circuits. The power source circuit is coupled to the first and second transistors. The first DC level setting circuit provides a second gate voltage for a second gate of the second transistor according to a first DC voltage and the first AC component. The second DC level setting circuit provides a first gate voltage for a first gate of the first transistor according to a second DC voltage and the second AC component. The second gate voltage and first gate voltage are lower than the voltages of the first and the second signal respectively.
