Abstract
A hybrid circuit has a transfer function having three zeros and four poles that are realized using only two fully-differential amplifiers in combination with a small plurality of resistors and capacitors, making the hybrid suitable for use with a communication medium comprising capacitively coupled non-ideal transformers and transmission lines while providing remarkably good hybrid rejection without the use of inductors.
