    Abstract: A write driver (510;1210) driving a write current (IL) through a head connected to the write head (570;1270) by an interconnect (560;1260). The write driver (510;1210) includes a circuit (514.556;1214,1256;1340) matching output resistance to the odd characteristic impedance of the interconnect (560;1260) and a voltage boosting circuit (512;1212). The voltage boosting circuit (512;1212) is connected between a supply voltage (VCC) and a voltage reference (VEE), and includes at least a current generator (440,1140), such as a MOS transistor, connected to the input node (422;1122) of a single capacitor (420;1120).
