Abstract
HYPRES, in collaboration with University of Waterloo, proposes to develop a unique mixed-signal integrated circuit (IC) technology for radio frequency (RF) receivers. Using Niobium ICs, we have developed a family of receiver front-ends capable of direct digitization of RF signals up to microwave frequencies (20 GHz). Using Josephson junctions as active devices, this Digital-RF technology features high-linearity analog-to-digital converters (ADCs) and ultrafast large-scale digital circuitry employing rapid single flux quantum (RSFQ) logic. Here, we propose to augment this Nb IC technology by incorporating microelectromechanical systems (MEMS) analog RF devices. Specifically, our objective is to develop a high-linearity, low-loss, rapidly tunable band-stop filter to excise high-power interferers in front of the ADC. This new technology will enable integration of MEMS analog filters, ADC, and RSFQ digital circuitry on the same chip.
