'Switched-Current Wave Group Delay Equalizers'

Xie, Yan and Al-Hashimi, Bashir (2004) 'Switched-Current Wave Group Delay Equalizers' accepted by IEE Proceedings of Circuits, Devices and Systems

Record type: Article


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
