This article describes the design of integrated linear group delay filters for analog signal processing (ASP) applications and their implementation through constant-resistance lattice and bridged-T networks. Unlike previously published works, our design method uses a recursive procedure as the basis for the synthesis of a suitable transfer function. Thanks to this method, filters with a more linear group delay characteristic and flat magnitude response can be obtained.Two filters are designed in a 0.13-μm BiCMOS technology to demonstrate the method: a balanced lattice with a negative slope and an unbalanced bridged-T of positive slope.
