A new scheme for a compact, continuously tunable terahertz source based on photoconductive antenna arrays is presented. Narrowband terahertz radiation is generated by superposition of time-delayed wideband radiations from an array of sub-picosecond photoconductive antennas. We demonstrate an 8 μW average power, radiation bandwidth of 0.05 THz, and a tuning range of 0.65–1.4 THz, through a 2.5×10 mm...
An analog-to-digital converter (ADC) architecture that extracts the required quantization energy directly from the input analog signal and sampling clock through a spatial quantization scheme is presented. We experimentally demonstrate 8-level quantization consuming only 7.2pJ per quantization operation with 18GHz bandwidth. Measured 8ps full-width half-maximum photodetector output voltages, promises...
