Abstract:
An active R-C circuit comprising:a fully-differential amplifier; a pair of single-ended buffers; and a resistor-capacitor network connecting the output of the fully-differential amplifier to the inputs of the pair of single-ended buffers configuring the fully-differential amplifier, pair of single-ended buffers and resistor-capacitor network as a hybrid devoid of inductors and realizing a transfer function providing substantial elimination of a receiver path signal associated with a communication medium comprising capacitively coupled non-ideal transformers and transmission lines; wherein the transfer function is represented by the relationship h=k&af;(s-z1)&it;(s-z2)&it;(s-z3)(s-p1)&it;(s-p2)&it;(s-p3)&it;(s-p4),â€ƒwherein s=j(2&pgr;f), p=poles and z=zeroes.
