inverters 136 and 138 transitions from a high to a low voltage in addition by connecting inverters 136 and 138 in parallel additional current is available to drive transformer 150 the output from d flip flop 118 output q 130 and output q 132 is a square wave the output from output q 130 terminal is opposite to the output from output q 132 terminal e g when output q 130 terminal output is a high voltage level the output of output q 132 is a low voltage level the square wave is input to inverters 136 and 138 at node 128 the output signal from inverters 136 and 138 u201c inverted u201d at node 140 compared to the input signal at node 128 the output signal from inverters 136 and 138 at node 140 are input to primary winding 148 of transformer 150 transformer 150 includes a primary winding 148 and a secondary winding 152 both primary winding 148 and secondary winding 152 have the same number of turns therefore transformer is a 1 1 transformer in one embodiment transformer is not a step up or a step down transformer primary windings 148 are in the opposite direction of secondary windings 152 causing the polarity of the voltage at the terminals of secondary winding 152 to be opposite the polarity of the.
