Patent ID: 7274245

Claim:
A transfer circuit comprising: an input line for receiving an input voltage; an output line for supplying an output voltage; a control line for receiving an enable signal; a CMOS device for supplying a switching voltage; a feedback line for supplying a feedback of said output voltage to said CMOS device, wherein said CMOS device is connected to said control line for receiving said enable signal and for controlling said switching voltage based on said enable signal to have one of a first voltage level and a second voltage level, said second voltage level being equivalent to said feedback of said output voltage; an NMOS transistor having a gate connected to said CMOS device for receiving said switching voltage and having a drain connected to said output line for supplying an equivalent of a standby voltage to said output line when said switching voltage is at said first voltage level; and a first PMOS transistor having a source connected to said input line and a drain connected to said output line for supplying an equivalent of said input voltage to said output line when said switching voltage is at said second voltage level.
