Abstract
Matrix-based methods for the design of transconductor ladder filters are presented. These allow the realisation of any bandpass or lowpass prototype using only one or two values of transconductance. The new methods are illustrated by experimental results from a 1 MHz elliptic lowpass filter, a 400 kHz elliptic bandpass filter, a 400 kHz Chebyshev bandpass filter, and a PLL frequency-control loop, all fabricated in a 1 μm CMOS process
