ABSTRACT:
A transmission line driver circuit (10) includes a signal input (12). A first capacitor (28) stores a first voltage level corresponding to a first of two possible bit values of an input signal. A second capacitor (44) stores a second voltage level corresponding to a second of the possible bit values. First and second voltage supply sources (24, 42) are selectively and respectively coupled to the first and second capacitors (28, 44) for recharging these capacitors to their respective voltage levels. A transmission line (50) is coupled to an output of a switching circuit. The switching circuit is operable to couple the first capacitor (28) to the switching circuit output (34) in response to receiving an input signal of a first bit value. The switching circuit is further operable to couple the second capacitor (44) to the output (34) in response to receiving an input signal of a second bit value. The bit value is thereby propagated onto the transmission line (50).
