DAM STRUCTURE FOR CENTER-BONDED CHIP PACKAGE |
摘要 |
The present invention provides a method and a circuit for driving control electrodes between a reset voltage and an adjustable extraction voltage. The circuit includes a reset switch having first and second terminals with the first terminal being connected to a high voltage source. A plurality of set switches, each capable of assuming an on state and an off state connected such that a first terminal of each set switch is connected to a corresponding one of the control electrodes and a second terminal is connected to a low voltage source. The circuit further includes a plurality of diodes, each being connected between the second terminal of the reset switch and a corresponding one of the control electrodes. A plurality of current sources, each current source being capable of assuming an enabled and a non-enabled state, are connected between a high voltage source and a corresponding one of the control electrodes to supply a constant current to the control electrodes and thereby adjust the extraction voltage at the control electrode.
