A first‐order Sinh‐Domain allpass filter topology is introduced in this paper. It is constructed from a class‐AB current mirror and appropriately configured non‐linear transconductor cells. Due to the inherent class‐AB nature of Sinh‐Domain filters, the proposed topology offers the capability for handling currents at levels greater than that of the dc bias current level. Also, it offers the well‐known features of companding filters such as electronic adjustment of its frequency characteristics and the capability for operation in a low‐voltage environment. In addition, a four‐phase sinusoidal oscillator design example has been provided. The behaviour of the proposed topology has been evaluated and compared with other already known configurations, where the most important performance factors have been considered.
