Abstract :
This paper presents a low-voltage, low-power, variable gain transmitter front-end for 900 MHz ZigBee applications, in a 0.25 mum CMOS technology. The up-mixer achieves a wide range-gain variation by adopting a novel transconductance stage. The measurements show the overall transmitter front-end conversion gain of 16 dB, dB-linear gain variation of over 46 dB with the linearity error less than plusmn0.5 dB, output P-1dB of 2 dBm, while dissipating 3 mA from 1.25 V supply
