In this paper, a scheme for the tuning of filters is proposed, where filters are time-shared between a signal path and a tuning path, so that each filter in a system is individually tuned.Abstract:
A scheme for the tuning of filters is proposed. In it, filters are time-shared between a signal path and a tuning path, so that each filter in a system is individually tuned. An accurate system frequency response can thus be achieved which does not rely on tight matching between filters.read more

Design of a 15-MHz CMOS continuous-time filter with on-chip tuning
TL;DR: In this paper, a fifth-order CMOS continuous-time Bessel filter with a tunable 6-to 15-MHz cutoff frequency is described, which achieves a dynamic range of 55 dB while dissipating 96 mW in a 5-V 0.9-mu m CMOS process.

Integrable analogue active filters for implementation in MOS technology
R. Schaumann,J.R. Brand +1 more
TL;DR: In this article, a design method for MOS-compatible analogue active filters that use only integrating amplifiers and ratios of capacitors is discussed, which retain most of the implementation advantages of sampled-data switched-capacitor filters, but are complementary to switched capacitors in providing better and more predictable performance at high frequencies.
