'Switched-Current Wave Group Delay Equalizers'
To improve the elliptic filters step response, group delay equalizers are often cascaded with the filters. This paper describes the design of switched-current (SI) group delay equalizer using wave synthesis technique. This design is based on a new all-pass circuit, where the poles are generated using wave structures. Simulation results are included demonstrating that the 3rd-order SI group delay equalizer can reduces the amount of overshoot in 100kHz elliptic low-pass filter step response by 50%. This is as a result of reducing the filter group delay variation from 2.29us to 0.32us when the group delay equalizer is employed

Abstract
To improve the elliptic filters step response, group delay equalizers are often cascaded with the filters. This paper describes the design of switched-current (SI) group delay equalizer using wave synthesis technique. This design is based on a new all-pass circuit, where the poles are generated using wave structures. Simulation results are included demonstrating that the 3rd-order SI group delay equalizer can reduces the amount of overshoot in 100kHz elliptic low-pass filter step response by 50%. This is as a result of reducing the filter group delay variation from 2.29us to 0.32us when the group delay equalizer is employed
