  • Abstract
    A monolithically integrated 5th order lowpass filter with a tunable cutoff frequency is presented. The cutoff frequency can be tuned via a control voltage between 30 kHz and 180 kHz. This circuit may serve as channel selecting filters in direct conversion receivers for various cellular radio services with different bandwidth (e.g. IS-54, GSM, etc.). The main design goals are low power consumption, a large tuning range, good linearity and a high dynamic range
