Description
Summary:This paper presents a 140GHz zero-IF receiver for terahertz array systems using TSMC 40nm CMOS process. On the one hand, the currents of the active mixer and the low-noise amplifier are partially multiplexed, while the currents of the oscillator and the frequency multiplier are fully reused, in order to reduce the power consumption. On the other hand, the compact layout design allows a receiver area of 0.4 \text{mm}^{2} (including pads). Simulation results show that the receiver achieves an SSB NF of 11.2dB and an \text{IP}_{\mathrm{l}\mathrm{d}\mathrm{B}} of −13.8dBm, with 10dB conversion gain and 10GHz bandwidth, while requiring only 48mW of power consumption.
