Negative Group Delay Theory of a Four-Port RC-Network Feedback Operational Amplifier

Negative Group Delay Theory of a Four-Port RC-Network Feedback Operational Amplifier

An innovative negative group delay (NGD) theory based on a unity direct chain feedback (UDCF) circuit topology is developed in this paper. This NGD circuit is an active cell constituted by an operational amplifier in feedback with a four-port RC-network. This NGD circuit theory is developed based on...
