摘要

集成阻挡检测器的0.1-0.6GHz斩波开关电容射频接收机具有中心频率可调、滤波器阶数可编程和高带外线性度的特点。射频阻抗匹配、高阶OB干扰滤波和闪烁噪声斩除仅由无源SC电路实现。34-80mW 65nm接收器实现35dB增益，+31dBm OB-IIP3， +15dBm B1dB和4.6-9dB NF。该滤波器阶适用于具有响应时间为1us的阻塞检测器的阻塞电源。

A chopping switched-capacitor RF receiver with integrated blocker detection, +31dBm OB-IIP3, and +15dBm OB-B1dB

A 0.1-0.6GHz chopping switched-capacitor RF receiver with integrated blocker detector features tunable center frequency, programmable filter order, and very high out-of-band linearity. RF impedance matching, high-order OB interferer filtering, and flicker-noise chopping are achieved by passive SC circuits only. The 34-80mW 65nm receiver achieves 35dB gain, +31dBm OB-IIP3, +15dBm B1dB, and 4.6-9dB NF. The filter order is adapted to blocker power with a blocker detector with a 1us response time.
