This paper reports on the design of a 140 GHz on-off keying (OOK) receiver using 40 nm LP CMOS process. The receiver has three channels with a combiner to combine the outputs. Each channel contains an OOK demodulator and a broadband baseband amplifier. Dual g m boosting and self-biasing techniques have been proposed in this design of the OOK demodulator. The baseband amplifier combines capacitive peaking and inductive peaking techniques to extend its bandwidth. The proposed receiver occupies a silicon area of 0.71 mm 2 and each channel achieves a maximum data rate of 15 Gbps with a power consumption of 34 mW, corresponding to an energy efficiency of 2.26 pJ/bit.
