Abstract: This paper describes full cmos continuous time filter design techniques which can meet the specifications commonly set for GSM applications. First several cmos filter design techniques are overviewed. The OTA-C technique is discussed to some more detail. To overcome the main drawback of the lower total harmonic distortion in OTA-C techniques very linear operational transconductance amplifiers (OTA) are required. Such an OTA, together with the applied linearisation techniques is discussed. To fulfil high accuracy in cut-off frequencies of the filter an active tuning system is necessary. A new on-chip tuning system is presented. The paper concludes with a practical design example for the GSM system. Therein the different OTA-C techniques discussed are illustrated.
