A programmable pulse slimmer system for a low pass ladder filter includes a filter input current source for providing to a low pass ladder filter the input signal to be filtered; and a high frequency boost current source for injecting into the low pass ladder filter forward of the first inductor device a high frequency load current which is a scaled inverse replica of the input signal to provide gain at the high frequency end of the low pass band of the low pass ladder filter.
