Abstract:
This article presents a low-power (LP), compact, wideband (WB) low-noise transconductance amplifier (LNTA)-first receiver (RX) designed for software-defined radios (SDRs). It comprises the LNTA, frequency divider, mixer, and trans-impedance amplifier (TIA). The LNTA utilizes a common gate (CG)-common source (CS) structure without on-chip inductors and incorporates gm-boosting and …
