This paper presents the design and simulated performance of a novel intermediate-frequency variable-gain amplifier for Wideband Code-Division Multiple Access transmitters. A compensation technique for parasitic coupling is proposed which allows the very high dynamic range of 85 dB to be attained using a single variable-gain stage. Temperature compensation and decibel-linear control are achieved by means of a proper bias network which provides a lower than +/-1.5 dB gain error over full temperature and gain ranges. The device has a 600 MHz bandwidth and drains up to 5.5 mA from a 2.7-V power supply. A -146-dBm/Hz output noise and -55-dBc adjacent-channel leakage power ratio are. obtained under maximum gain conditions. Circuit simulations are based on a 0.8-mum 46-GHz-f(T) silicon bipolar technology. |
