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.Abstract:
A fifth-order CMOS continuous-time Bessel filter with a tunable 6- to 15-MHz cutoff frequency is described. This fully balanced transconductance-capacitor (G/sub m/-C) leapfrog filter achieves a dynamic range of 55 dB while dissipating 96 mW in a 5-V 0.9- mu m CMOS process. The author reviews the disk drive application and filtering requirements, and explains why the G/sub m/-C continuous-time filtering approach was used. The on-chip master-slave tuning system uses a voltage-controlled oscillator (VCO). Experimental results are presented. >read more

Log-domain filtering: an approach to current-mode filtering
TL;DR: A novel approach to filter design, based on Adams' ‘log-domain’ filters, is proposed that yields a truly current-mode circuit realisation and, by introducing an exponential map on the state-space description of the desired linear system, a log-domain filter can be fully realised.

Multiple-Input Describing Functions and Nonlinear System Design
TL;DR: The theory of automatic control has been advanced in important ways during recent years, particularly with respect to stability and optimal control, but these theories do not, however, lay to rest all questions of importance to the control engineer.
