FANZHEN MENG et al: LOW POWER BALUN-LNA FOR SUBSAMPLING ARCHITECTURE OF RECEIVER
نویسندگان
چکیده
A single-ended-to-differential conversion balun-LNA is proposed in this paper for subsampling architecture of receiver. The LNA adopts the inductively degenerated common-source common-gate (cascade) structure with noise canceling technique, which can achieve high gain and low noise figure without extra components and power consumption. For the subsampling receiver of IoT narrowband application, the LNA is integrated in 65 nm CMOS. It can achieve a noise figure of 1.5dB at the 780MHz, a differential voltage gain of 30 dB and gain and phase mismatch within 0.5 dB and 5o in the range from 775MHz to 785MHz, which is adequate for most of IoT applications. The proposed LNA consumes about 1.6mA with 1.2 V voltage supply.
