Abstract
A new four-frequency-shift keying (4FSK)
transceiver (TRX) at 145–185-GHz operation frequency is
presented. The proposed non-coherent TRX is a fully integrated
bit-in–bit-out communication system without the need for
separate modulators/demodulators (modems). The transmitter
(TX) core includes only one voltage-controlled oscillator (VCO),
which can generate four different frequencies based on the
two parallel streams of binary data at its input. The receiver
