A new tuning loop is presented for tuning continuous time filters. This tuning loop is applicable mainly to all MOS circuits, in which the tuning range of the filter is severely restricted. It is shown that the tuning loop helps in operating the filter at the desired power efficiency levels, and also extends the tuning range of the filter.
