摘要An all in one integrated 315MHz ASK UHF receiver is proposed in this paper. This receiver has several characteristics, first RF-in data-out all in one function, second without any spiral inductor and final filter all on chip (Crols et al., 1995; Wilson et al. 1991). We design a monolithic ultra-high frequency (UHF) receiver including RF front-end, intermediate-frequency (IF) stage and base-band stage. The RF front-end end include single end low-noise amplifier (LNA) without on-chip spiral inductors and a mixer which down-converters the LNA output to 2.25MHz IF. The IF stage includes 1MHz band pass filter, variable-gain amplifier (VGA), automatic gain control (AGC) loop and peak detector. The base-band stage includes on-off keying (OOK) demodulator and slicing comparator to output digital signal. The UHF receiver was implemented in a UMC 0.5μm CMOS process. The receiver sensitivity is -73dBm and 2.4kbits data rate. The chip consumes 13mA and size in 1370×1370μm2. In the future, we will increase the sensitivity to -100dbm, then this receiver will be manufactured into product. Thus, the design of a high sensitivity and low cost UHF receiver will be the most important area for the future work.
