Front-end circuit with electro-static discharge protection
摘要:
A termination circuit configured to provide electrostatic discharge (ESD) protection is provided. Termination sub-circuits are coupled in parallel, each including respective pull-up and pull-down circuits. Each pull-up circuit has two transistors of a first type coupled in series between a data input and Vdd, a gate of one of the two transistors being coupled to a control input and a gate of the other one of the two transistors being coupled to a first enable input of the termination sub-circuit. Each pull-down circuit has two transistors of a second type coupled in series between the data input and Vss or ground, a gate of one of the two transistors being coupled to the control input and the gate of the other one of the two transistors being coupled to a second enable input of the termination sub-circuit.
