What is A Novel Multifunctional Negative Group Delay Circuit for Realizing Band-Pass, High-Pass and Low-Pass about?

A novel multifunctional negative group delay circuit is proposed. The circuit can realize three different negative group delay functions, including band-pass, high-pass and low-pass, which meet different conditions with capacitance, inductance and resistance. Analytical design equations are provided. The effects of different element values on the bandwidth, cut-off frequency and the minimum negative group delay of the circuit are analyzed. According to this design method, the negative group delay circuit is designed and fabricated. Simulation and measurement results are in agreement. It has good negative group delay characteristics. The feasibility of the design method is verified.
