This paper presents the compensation method for the active-RC integrators employing unbuffered low-gain opamp suitable for low-voltage low-power designs. The compensated integrators are then connected together in the cross-cascade fashion to synthesize the compact ladder-based fifth-order Chebyshev filters with 100-kHz and up to 10-MHz bandwidth, operating(More)
An ultra low-power low-voltage active-RC filter design with on-chip automatic tuning system is presented. It is based on the compensation method for compact low-gain amplifier and can be operated at supply voltages down to 0.5 V. Charge pump phase-locked loop technique has been adopted for automatic tuning system. A fifth-order Chebyshev low-pass filters(More)
