This paper presents a novel approach to the design of integrated reconfigurable and programmable analog filters for commercial mobile applications. The method is described in the specific context of an analog filter, dedicated to multi-mode receiver front ends employing direct frequency conversion. The filter has been designed using state variables and leap-frog OTA-C techniques, features programmable order, digitally variable frequency parameters and wide linear range, while supporting several standard approximations.</p
