Abstract
A fixed impedance in parallel with a variable impedance form a high pass filter with a capacitor. An input signal is provided to the capacitor. The value of the variable impedance is controlled in relation to the magnitude of a dynamic DC offset in the input signal to control the corner frequency of the high pass filter, providing a higher corner frequency and more rapid suppression of dynamic DC offset for larger dynamic DC offset magnitudes.
