A 1.44mm2 4-channel UWB beamforming receiver with Q-compensation in 65nm CMOS
A compact 4-channel UWB beamforming receiver is proposed by employing low-Q LC delay with Q-compensation technique. The delay chain achieves 224 ps delay range with 7 ps delay resolution. It occupies area of 1.44 mm2, which is 7 times smaller than other UWB beamformer with LC delay. To compensate the losses generated by low Q inductors and minimize the power consumption, current reuse LNA and buffers are adopted. The receiver covers scanning angle of ±48o with spatial resolution of 4o under antenna spacing of 3 cm while consuming 288 mW.
