Abstract—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 op-
erating under indoor multipath scenarios, resolving channels with
up to 32 ns multipath delay spread. It uses mixed-signal equal-
ization and carrier recovery in order to minimize the dynamic
range requirements of the analog-to-digital converter circuitry.
