A Low-Power Analog Baseband Section for 60-GHz Receivers in 90-nm CMOS
Abstract
A low-power analog baseband section suitable for 60-GHz receivers using orthogonal frequency-division multi- plexing (OFDM) with 16 quadrature amplitude modulation (16-QAM) modulation is presented in this paper. Power ef- ficiency is achieved by combining active-RC with source-follower-based topologies in order to synthesize a custom sixth-order transfer function. The complete chain consists of the cascade of a first-order transimpedance amplifier with finely programmable gain, a fourth-order source-follower-based filter, and a coarse gain first-order programmable gain amplifier. The prototype is imple- mented in 90-nm CMOS. It achieves a 1-GHz cutoff frequency and programmable gain from 0 to 20 dB with 1-dB step control, drawing 9.5 mA (0–9 dB gain range) or 10.8 mA (10–20 dB gain range) from a 1-V supply. An 8.2-dBm third-order input intercept point and a 145-dBm/Hz input-referred noise power density are measured at 0- and 20-dB gain, respectively. The entire circuit occupies an area of 390x400um^2.
