A fully integrated 0.35 /spl mu/m CMOS MMIC amplifier for short range 433 MHz ISM band transceiver applications

Abstract

A two-stage amplifier is implemented by utilizing Austria Micro System (AMS) 0.35 /spl mu/m CMOS technology with double poly and triple metal layers. The highly linear amplifier consumes 20 mA from a 1.8 V power supply and achieves a power gain of 26 dB with an OIP3 of 14.5 dBm. The fully integrated compact design is realized on only 2 mm/sup 2/ chip area including bias circuitry and power-down mode.
