or any combination of these elements for example element 106 may also include a resistor and or a mos in case of a mos as an example the gate of the mos may be coupled to various elements for example source of the mos or node 107 or the divider circuit 102 in another example node of the diode chain 106 is coupled to the divider circuit 102 as shown in the embodiment of fig2 elements 112 and 114 are capacitor dividers of nmos implementation between the two capacitors to divide the voltage between the anode and the cathode to a certain value also only two elements nmos 112 and 114 are illustrated as voltage dividers however one of ordinary skill will appreciate that more than two elements in series could be used it is noted that even though nmos devices are used as voltage dividers one of ordinary skill in the art would appreciate that circuit 112 and 114 may preferably consists of other elements such as resistors pmos devices capacitors such as a varactor an n doped capacitor ncap a metal oxide metal mom capacitor a metal insulator metal mim capacitor parallel connection of resistor and capacitor reverse biased diodes inverters and like or combination of these elements according to one embodiment of the present invention parameters such as number of triggering elements such as diodes in the example of fig2 and ratio of the voltage of the divider devices will influence on the trigger voltage of the circuit 102 as will be described in greater detail below since in the example of fig2 the voltage dividers 112 and.
