ABSTRACT:
Often programmable gain attenuators (PGAs) are combined with high pass filters. Adjustment of the highpass filter however can have unintended effects, such as changing the step size of the PGA. By placing the resistance of the highpass filter in parallel with a programmable attenuator divider, the steps of the PGA can be minimally affected as the highpass frequency is adjusted.
