An RF IC for a 1.1-V VHF paging receiver is developed. In order to reduce the number of components, it employs direct-conversion frequency shift keying (FSK) architecture. The RF IC adopts two new gain control circuits so as to achieve a wide input dynamic range with only a 1.1 V power supply. One is a low-voltage, low-noise, low-distortion RF amplifier and the other is a low-voltage AGC amplifier. By applying these new circuit technologies, the RF IC achieves a voltage gain of 50.5 dB and a noise figure of 4.3 dB with only 2.0 mW power consumption. Overall, the paging receiver achieves a high sensitivity of -130 dBm and low-intermodulation sensitivity of -37 dBm with bit error rate of 3×10^<-2>. This paper describes the new high-frequency low-voltage circuit technologies applied in the RF IC.
