Write driver with H-switch synchronizing transistors

A write driver for driving a transducer having first and second terminals, the write driver comprising:

• first and second voltage supply terminals;
• an H-switch having a first pull-up transistor connected between the first voltage supply terminal and the first transducer terminal, a second pull-up transistor connected between the first voltage supply terminal and the second transducer terminal, a first pull-down transistor connected between the first transducer terminal and the second voltage supply terminal, and a second pull-down transistor connected between the second transducer terminal and the second voltage supply terminal, wherein each transistor includes first and second terminals and a control terminal;
• at least one data input terminal for receiving data input signals;
• a bias circuit connected between the data input terminal and the control terminals of the first and second pull-up transistors and the first and second pull-down transistors for switching the transistors between conducting and non-conducting states as a function of the received data input signals;
• a first synchronizing transistor having first and second terminals which are connected between the control terminal of the first pull-down transistor and the second voltage supply terminal, the first synchronizing transistor further having a control terminal connected to the bias circuit such that the first synchronizing transistor conducts current away from the control terminal of the first pull-down transistor when the first pull-down transistor is switched to the non-conducting state;
• and
• a second synchronizing transistor having first and second terminals which are connected between the control terminal of the second pull-down transistor and the second voltage supply terminal, the second synchronizing transistor further having a control terminal connected to the bias circuit such that the second synchronizing transistor conducts current away from the control terminal of the second pull-down transistor when the second pull-down transistor is switched to the non-conducting state.
