Abstract :
A synthesis procedure of general nth-order allpass voltage transfer functions using solely voltage differencing buffered amplifiers (VDBAs) and capacitors with the signal-flow-graph design method is described. It has been shown that the proposed structure employs n VDBAs and n capacitors for the realization of any nth-order voltage transfer function. As an illustrative example, the third-order voltage-mode allpass filter has been designed and simulated using PSPICE.
