Summary In this letter, all possible single transistor RC‐only second‐order allpass filters obtainable from a four impedance common‐source topology are reported. It is shown that there are only seven such filters with only one of them being a minimum component canonical 2R‐2C filter. Two of the found filters are designed and simulated in a 65‐nm CMOS process.
