Abstract
A high frequency clock signal generator (10) is disclosed. The clock signal generator includes a power supply (12, 14), a first resonant tunneling diode (18) coupled to a first terminal of the power supply and an output node (22), and a second resonant tunneling diode (20) coupled to the output node (22) and a second terminal of the power supply. A signal source is coupled to the output node (22) and periodically switches the first and second resonant tunneling diodes (18, 20) between a first state and a second state. The signal source comprises an oscillating signal generator (26) and a transmission line (28) coupled to the output node (22) of the clock signal generator. The oscillating signal generator (26) produces an oscillating input signal, which is reflected by the transmission line (28). The resonant tunneling diode configuration provides rapid voltage swings at the output, thus allowing the generation of a high frequency clock signal of 25 GHz or more.
