Abstract :
We present a symmetric reciprocal (bilateral) gain-compensated negative group delay circuit, operating at 310 MHz and exhibiting a group delay of -0.5 ns. The circuit allows the conditionally stable gain-compensated propagation in both directions. The analytically predicted results are validated with frequency domain measurements, and stability is examined. Application of the circuit to a bilateral, gain-compensated constant phase shifter design is demonstrated.
