offset voltage compensation in baseband in a radio receiver path is achieved by control and programming signals which are required in any case to set the desired states in the circuit module . for this purpose a sequencer is started which is integrated on the module and provides additional control signals that are defined in time , without any additional computation power being required from a separate baseband processor . the offset voltage compensation can be used in receiver and transceiver chips for portable mobile radios , for example for gsm or pcn / pcs .
