摘要：
A synthesis procedure based on the signal flow graph is given for generating second-order active filters using a minimum number of operational transconductance amplifiers and grounded capacitors. The pole quality factor and pole frequency sensitivities are studied for the proposed filters. Furthermore, the limitations on input signal amplitude are studied and a simple formula is derived for the input signal amplitude not causing clipping and slew-rate-limiting problems.
