In battery-powered medical instrumentation, the resolution and signal bandwidth of analog-to-digital converters (ADCs) have to be adapted to the needs of the application to avoid power wastage. This paper presents a reconfigurable successive approxim

A MOSFET-only filter is described which employs an amplifier-regulated cascode structure to realize both conductance and transconductance, while the required capacitors are realized by MOSFET gate capacitance. The filter configuration is such that bo

A new biquad configuration with inherent low sensitivities and low capacitor area for high- Q equalizers is proposed. A simple procedure for optimal design is presented and the design example is compared with that of Laker et al [1]. The results show

The capacitance ratio constraint for equal op-amp dynamic range is derived in this paper for a collection of important biquad configurations of all filter types. This completes the set of explicit design constraints for the determination of capacitan

A phase-splitting network is another type of circuit that is suitable to be integrated using the switched-capacitor (SC) technique. However, using existing all-pass SC configurations to realize such networks results in excessive capacitance spread be
