  • Multiplexer circuit, and method and system for generating layout diagram corresponding to same
    Patent number: 10680609
    Abstract: A multiplexer circuit, of power supply (PS) voltages, includes: finger circuits correspond to the PS voltages, each selectable finger circuit (A) having an input node which is finger-circuit-specific and an output node which is common to the finger circuits, (B) including an anti-leak transistor of a first conductivity (C1) type, a selector transistor and a driver transistor transistors of a second conductivity (C2) type connected in series between the input node and the output node, and (C) being configured to receive a corresponding one of the PS voltages from the input node, and provide, if selected, a first version of the corresponding PS voltage to the output node.

  • Multiplexer circuit, semiconductor device for multiplexing voltages, and method of operating same
    Patent number: 10298228
    Abstract: A multiplexer circuit, of power supply (PS) voltages, includes: selectable finger circuits corresponding to the PS voltages, each selectable finger circuit: having an input node which is finger-circuit-specific and an output node which is common to the finger circuits; being configured to receive a corresponding one of the PS voltages from the input node and, if selected, provide a first version of the corresponding PS voltage to the output node. Each of the selectable finger circuits includes: a non-enhancement mode transistor of a first conductivity (C1) type (C1-type transistor) and enhancement mode first and second transistors of a second conductivity (C2) type (C2-type transistor) connected in series between the input node and the output node.
