Abstract
An ultra-low-power RF envelope-detection radio has
been designed for low-power shor t-range wireless applications.
It introduces an interference rejection technique that improves
the in-band selectivity by 24.5 dB. The transmitter adopts the
power-efficient direct-modulation architecture, and the r eceiver
maintains the simplicity and low power consumption of envelope
detection receivers. In the 915 MHz ISM band at 10 kbps the
transmitter output level reaches
3 dBm with 33.9% global
efficiency, wh
