Abstract :
Direct tuning techniques of continuous-time filters for mobile radio receivers are discussed. Different design aspects and the effect of nonidealities are considered. A single-shot tuning scheme which is based on digital control word calculation algorithm is proposed for cases (CDMA) where sufficient time cannot be allocated for feedback based tuning as in time-division multiplexed radio systems (TDMA)
