Abstract
This paper presents a circuit design and implementation for the analogous filter and amplifier sections of a direct conversion receiver. Dual-mode operation is achieved by switching the LP-filters' cut-off frequency to meet DECT and DCS 1800 specifications alternatively. An op-amp-based integrator loop filter structure is used to perform low-noise, low-voltage and low-power operation. The circuit is fabricated using a 1.5 BiCMOS process. Including a DECT demodulator and a RSSI circuit the whole two-channel circuit drains 4 mA from a 3 V power supply. 1 Introduction The increasing number of available mobile communication networks offers the necessity to provide equipment for several standards. It's desirable from the user's point of view to communicate in different networks like GSM, DCS 1800 and DECT with only one single handset. Primarily it is intended to combine the access to a mobile communication network offering complete attainment with the access to a local cordless envi...
