Abstract
This article presents a 2.4-GHz 65-nm CMOS fully
integrated nonlinear mixer-first receiver (RX) for the Internet
of Things (IoT). To power efficien tly improve the in-band inter-
ference resilience, we propose an inverter-based envelope-biased
low noise amplifier (IBEB-LNA), which exploits dynamic biasing
voltage generated from its input signal envelope to suppress the
interferer in the amplitude domain. The achievable carrier-to-
interference ratio (CIR) at ±3a n d ±5M H zi s −45/−59 and
