  • Circuit for receiving an AC coupled broadband signal
    Patent number: 6741140
    Abstract: A receiving circuit having a termination impedance and an equalization capacitor. The receiving circuit is connectable to a signal source having a source impedance through a DC (direct current) blocking capacitor. The value of the equalization capacitor is chosen such that voltage spikes otherwise caused by the blocking capacitor are eliminated. The receiving circuit is especially useful in distributed electronic amplifiers and electro-optic modulators.
