In this way, the high-voltage selecting circuit can correctly generate the output voltage according to the first input voltage and the second input voltage, and avoid the leakage current at the same time. | 09-29-2011 |
20110310514 | Electrostatic discharge protection circuit - An electrostatic discharge (ESD) protection circuit is coupled between a first terminal and a second terminal of an integrated circuit. The integrated circuit receives an input signal through the first terminal. The second terminal is coupled to a voltage source. The ESD protection circuit includes a PMOS transistor and a deep N-well NMOS transistor. When the static electricity is inputted to the first terminal, the static electricity flows to the voltage source through the corresponding parasitic diode and the corresponding parasitic bipolar transistor of the PMOS transistor and the deep N-well NMOS transistor. In addition, the input signal is not affected by the ESD protection circuit because the parasitic diodes of the PMOS transistor and the deep N-well NMOS transistor are reversely connected. Thus, the ESD protection circuit prevents the integrated circuit from being damaged by the static electricity and increases the operation voltage range of the input signal. | 12-22-2011 |
