A new ultra low-power Class-AB Sinh integrator is proposed here. The translinear companding integrator is based on hyperbolic-sine transconductors and uses only one grounded capacitor to implement a Class-AB integrator, which saves considerable chip area. Furthermore, the proposed circuit presents excellent performance with respect to power efficiency. To validate the circuit principle, the integrator has been simulated in standard 0.35μm CMOS technology and
