Abstract :
Low-IF technique for implementing transconductance networks (T-networks) in low-IF complex-filter is developed and a system solution for low-IF complex-filter with T-networks is also proposed in this paper. By implementing the T-networks in active-RC complex-filters, an area efficient solution for complex-filter design is presented in this paper. Compared with conventional active-RC complex filters, the layout size is reduced by about 50%.
