This paper presents the design of a negative group delay circuit (NGDC) using the filter synthesis approach. The proposed design method is based on a frequency transformation from a low-pass filter (LPF) to a bandstop filter (BSF). The predefined neg

It has been discovered that a trisection bandpass filter with mixed cross-coupling K 13 has flat group delay if the condition K 13 = 0 is satisfied, which occurs when magnetic Km and electric |K e | components of the coupling are equal. It has been p

At low-GHz frequencies, analog time-delay cells realized by LC delay lines or transmission lines are unpractical in CMOS, due to their large size. As an alternative, delays can be approximated by all-pass filters exploiting transconductors and capaci

To measure a filter's group delay in production is never an easy task and to measure the group delay characteristic in quick and timely manner is difficult to say the least. This paper will discuss a simple method that expands on the author's previou

This paper develops a three-terminal delay filter whose topology is an interconnection of only ideally lossless, coupled inductors and capacitors. In the absence of significant capacitive loading at the input and/or output ports, the proposed filter
