Abstract
One or more embodiments are directed to inter-integrated circuit (I2C) transmitters, receivers, and devices that utilize a stable reference voltage for driving a pre-driver of the transmitter and for driving a first input stage of the receiver. One embodiment is directed to a device A device that includes an inter-integrated circuit (I2C) transmitter and an I2C receiver. The I2C transmitter includes a driver coupled to an I2C data line, and a pre-driver coupled to a variable first supply voltage, a second supply voltage, and a reference voltage. The pre-driver is configured to output a control signal to a control terminal of the driver. The I2C receiver includes a first stage coupled to the I2C data line, the variable first supply voltage, the second supply voltage, and the reference voltage.
