Abstract :
A novel approach to programmable mixed-signal VLSI is presented that uses a pulse width modulated digital signal to encode analogue signal information. Signal communication between programmable analogue (and digital) signal processing cells is performed using this Palmo signal representation. A linear, programmable, voltage mode analogue CMOS Palmo cell is presented. Results from 1st, 2nd and 3rd order analogue Palmo filters, a 24 tap FIR Palmo filter, and a Palmo sigma-delta analogue-to-digital converter are presented
