This paper demonstrates a 240GHz wideband QPSK receiver in 65nm bulk CMOS. A direct-conversion mixer-first architecture is implemented with a 240GHz on-chip antenna. Wideband passive mixers at the front end employ a 240GHz LO and convert the received signal down to baseband. The baseband signal is then amplified using high gain, wide bandwidth amplifiers… CONTINUE READING
