Abstract:

An ultralow-power Bluetooth low energy (BLE)-compliant crystal-less clock-harvesting receiver is presented that uses the BLE advertising packets (APs) to calibrate an on-chip frequency reference with ±400 ppm initial frequency offset. The proposed front-end, fabricated in 22 nm FDSOI, is capable of pushing the frequency accuracy of the reference further to below ±40/±15 …

A 1-8 GHz, 190MHz BB BW Mixer-First Receiver With Bootstrapped Mixer Switches Achieving Over 16dBm In-Band IIP3

A 1-8 GHz, 190MHz BB BW Mixer-First Receiver With Bootstrapped Mixer Switches Achieving Over 16dBm In-Band IIP3 150 150
Author(s): Erwin Hardeveld, Ronan van der Zee, Bram Nauta

Abstract:

In this article, we propose a wideband mixer-first receiver with improved in-band (IB) linearity. It uses bootstrapped N-path mixer switches to achieve a constant on-state gate–source voltage for large IB signals. We analyze the tradeoff between on-state resistance and off-state subthreshold current in conventional mixer switches and introduce a …
