  • Semiconductor device having improved electrostatic discharge protection
    Patent number: 11916060
    Abstract: Various embodiments of the present disclosure are directed towards a semiconductor device. The semiconductor device comprises a source region and a drain region in a substrate and laterally spaced. A gate stack is over the substrate and between the source region and the drain region. The drain region includes two or more first doped regions having a first doping type in the substrate. The drain region further includes one or more second doped regions in the substrate. The first doped regions have a greater concentration of first doping type dopants than the second doped regions, and each of the second doped regions is disposed laterally between two neighboring first doped regions.

  • Termination circuit
    Patent number: 11444615
    Abstract: A termination circuit, including a termination resistor, a first switch circuit, a second switch circuit, and a control circuit, is provided. A first end of the termination resistor is coupled to a signal pad. A first end of the first switch circuit is coupled to a second end of the termination resistor. A first end of the second switch circuit is coupled to a second end of the first switch circuit. A second end of the second switch circuit is coupled to a reference voltage line. During a period when the second switch circuit is turned on, the control circuit turns on the first switch circuit with a bias voltage. During a period when the second switch circuit is turned off, the control circuit turns off the first switch circuit with a voltage of the first end of the first switch circuit.
