Abstract:
An integrated circuit includes an IO node, and an IO driver coupled thereto. The IO driver has a first driving circuit with a first PMOS transistor having a source coupled to a supply node and a gate coupled to receive a PMOS driving signal, and a first NMOS transistor having a source coupled to ground, a drain coupled to the drain of the first PMOS transistor, and a gate coupled to receive a NMOS driving signal. The IO driver also has a second driving circuit with a second PMOS transistor having a source coupled to the supply node and a gate coupled to receive a first delayed version of the PMOS driving signal, and a second NMOS transistor having a drain coupled to the drain of the second PMOS transistor, a source coupled to ground, and a gate coupled to receive a first delayed version of the NMOS driving signal.
