A fully integrated CMOS analog TCXO IC that is suitable for cellular phone and other applications is presented. It was designed in a 1.0 /spl mu/m CMOS process with an embedded EEPROM and operates from 2.5 V to 5.5 V supply voltage and consumes 1.1 mA at a 3.0 V supply voltage. The chip area is 2.38/spl times/1.93 mm/sup 2/. The temperature stability is better than /spl plusmn/2.5 ppm over -30 to 85/spl deg/C. Measured phase noise is -115 dBc/Hz and -135 dBc/Hz at 100 Hz and 1 kHz offset, respectively.
