Programmable switched-capacitor filter Conference Paper uri icon

abstract

  • A switched-capacitor filter with independent programmable gain at either low frequency, passband frequency and high frequency band is presented. The gain at each of these frequency bands is controlled by a capacitor bank. This universal second order switched-capacitor filter employs 3 operational amplifiers, 3 capacitor banks and some additional capacitors. Experimental results, from a breadboard, are in good agreement with the simulated and theoretical ones.
