The design and measured results of a 120 GHz / 140 GHz dual-channel amplitude shift keying (ASK) receiver are presented in this paper. Because a signal with very wide frequency width of over 10 GHz is difficult to process in a single-channel transceiver, a dual-channel configuration with channel selection is adopted in the proposed receiver. The proposed(More)
Indoor communication is desired in CMOS millimeter-wave transceivers. To realize indoor communication, a power amplifier with a high RF output power without compromising gain, bandwidth or power efficiency is required. In this paper, a strategic design for gate width selection and matching-network optimization is introduced. A power amplifier is fabricated(More)
We are developing monolithic pixel detectors utilizing a silicon-on-insulator (SOI) process commercially provided by OKI Semiconductor. Two main pixel sensors, INTPIX and CNTPIX, are being designed as signal integration and counting type devices, respectively. We describe the fabrication results including a buried p-well (BPW) technology recently adopted.(More)
