A 0.8V, 152 <italic>μ</italic>W, 433 MHz Mixer-First Receiver with a Self-Adjusted Frequency Tracking Loop
This paper presents a 433 MHz low-power receiver utilizing an N-path filter technique and a self-frequency tracking mechanism. Without the front-end amplifier, the mixer-first architecture can reduce power consumption significantly. A self-adjusted frequency tracking loop (SA-FTL) adjusts local osci...

| description | This paper presents a 433 MHz low-power receiver utilizing an N-path filter technique and a self-frequency tracking mechanism. Without the front-end amplifier, the mixer-first architecture can reduce power consumption significantly. A self-adjusted frequency tracking loop (SA-FTL) adjusts local oscillator (LO) frequency to approach input RF frequency automatically, thereby enhancing conversion gain and lowering return loss. The receiver, implemented in a <inline-formula> <tex-math notation="LaTeX">$0.18~\mu \text{m}$ </tex-math></inline-formula> CMOS process, achieves a sensitivity of −80 dBm at a bit error rate (BER) of 10<sup>−3</sup> and a data rate of 10 kb/s, while consuming <inline-formula> <tex-math notation="LaTeX">$152~\mu \text{W}$ </tex-math></inline-formula> from a 0.8V voltage supply. |
