A synthesis method of high-order voltage-mode all-pass filters is proposed in this thesis. Using (n+2) Second-Generation Current Controlled Conveyors (CCCIIs) and n grounded capacitors to synthesize high-order all-pass filters is presented first. The operational Transconductance Amplifiers and Capacitors (OTA-C) implementation is also obtained from the CCCII-C implementation by using a succession of nullator-norator transformation equivalences.
The synthesized all-pass filters simultaneously enjoy the following three important criteria：(i) the least number of active and passive components, (ii) the single-input active elements, and (iii) grounded capacitors.
HSPICE simulation with TSMC025 LEVEL49 parameters validate
the theory predictions.
