The paper discusses OTA-C implementation of fractional all-pass filter (FAPF) of order between 0 and 1. The filter is derived from OTA-C first-order all-pass topology proposed earlier. The filter uses a fractional order capacitor (FOC) which is realized using OTA as active block and grounded capacitors only. The FAPF filter of order 0.5 is realized using Cadence Virtuoso and simulated with Spectre RF. The results obtained from Cadence simulation were in correctness with theory.
