| description | A fully programmable multifunction filter is presented. The filter uses four operational transconductance
amplifiers and two capacitors. Analog switches are used to control the filter transfer function through
a microcontroller. The user is provided control over the cutoff (or centre) frequency of the filter by
controlling the auxiliary bias currents of the operational transconductance amplifiers via digital-to-analog
converters. The circuit can simultaneously provide three programmable transfer functions in a
single structure and can realize all the standard second-order filters. The circuit is attractive for VLSI
implementation. |
