Abstract
This paper presents a 76–84 GHz low-power 4-
element phased array receiver built using a 0.13 mB i C M O S
process. The power consumption is reduced by using a single-ended
design and alternating the ampli fiers and phase shifter cells to
result in a low noise figure at a low power consumption. A variable
gain ampli fier and an 11 trim bit are used to correct for the
rms gain and phase errors at diffe rent operating frequencies. The
phased array consumes 32 mW per channel and results in a gain of
