A 1Gbps mixed-signal analog front end for a 60GHz wireless receiver

A low-power, mixed-signal, baseband analog front end for 60 GHz 1 Gb/s wireless communications has been implemented in a standard 90 nm CMOS process. The receiver is capable of operating under indoor multipath scenarios, resolving channels with up to 32 ns multipath delay spread. It uses mixed-signal equalization and carrier recovery in order to minimize the dynamic range requirements of the converter circuitry, resulting in a low power consumption of 55 mW.
