Abstract
A high-speed A/D (analog-to-digital) converter based on the resonant tunneling diode (RTD) is described. This A/D converter takes advantage of the folding characteristic of the RTD to reduce the circuit complexity. The speed response of the A/D converter is improved by the fast latching action of the RTD digitizer. Simulations show that the 4-b A/D converter can have a sampling rate greater than 16 GHz. This performance represents a factor-of-five improvement over the best 4-b semiconductor A/D converter that has been reported
