Abstract

In this paper, a 5.8 GHz DC-coupled CMOS radar sensor transceiver chip with a bandwidth of 1 GHz for human activity detection was designed and fabricated in IBM 180-nm process. This transceiver chip adopts the direct-conversion quadrature architecture. Variable gain amplifiers are used to provide different gains for the baseband signal in order to carry out different applications. A novel adaptive DC tuning mechanism is implemented to eliminate frequency-dependent distortion and large DC offset at the receiver output. The size of the chip is 1.5 mm by 1.5 mm. Post-layout simulation results showed this transceiver chip has promising performance that is beneficial for human activity related detection.
