Abstract
An output driver includes a pullup driver, a pulldown driver and a resistive element. The pullup driver includes a first PMOS transistor having a source coupled to a first supply voltage and a gate receiving a first data representative of a transmitted data, and a second PMOS transistor having a source coupled to a drain of the first PMOS transistor and a gate receiving a first analog signal. The pulldown driver includes a first NMOS transistor having a source coupled to a second supply voltage and a gate receiving a second data representative of the transmitted data, and a second NMOS transistor having a source coupled to a drain of the first NMOS transistor, a drain coupled to a drain of the second PMOS transistor, and a gate receiving a second analog signal. The resistive element is coupled between the drain terminal of the second NMOS transistor and a pad.
