300 and a second inverter 302 are provided between the rc circuit 304 and the lvtscr 306 the first inverter 300 includes a pmos transistor 310 and a nmos transistor 312 and the second inverter 302 includes a pmos transistor 320 and a nmos transistor 322 the rc circuit 304 includes a resistor 330 and a capacitor 332 typically the second inverter 302 is larger than the first inverter 300 and can have a contact width of 100 u03bcm to 1000 u03bcm compared to the first inverter which may have a contact width of 1 u03bcm to 10 u03bcm while the embodiment of figure three involved the use of two inverters it will be appreciated that any even number of inverters could be used in yet another embodiment the positions of the resistor and capacitor were reversed to have the capacitor at the top in such an embodiment the drain will be initially held high and then be pulled down as the capacitor charges up thus to achieve the delay of the voltage pulse to the drain contact any odd number e g 1 inverter was used with the rc circuit it was found that the use of a double inverter as in fig3 provided similar voltage overshoot with a small rc circuit of 1 pf capacitor and 100 k resistor as was achieved using a large 100 pf capacitor without a double inverter in both embodiments however a clear benefit is achieved by separately controlling the drain and emitter to delay the voltage pulse to the drain under normal operation the capacitor will be fully charged thus the potential on the drain electrode will be equal to the.
