Abstract
An apparatus includes first and second input terminals configured to be coupled to one of multiple types of input sources. The apparatus also includes a diode and a resistor coupled in series between the first and second input terminals. The apparatus further includes a plurality of switches each coupled to at least one of the diode and the resistor. The switches are configured to be opened and closed to reconfigure the apparatus depending on the type of input source. The switches could include a first switch coupled to the first input terminal, a current source, and a first side of the diode. The switches could also include a second switch coupled to the current source, a second side of the diode, and a first side of the resistor. In addition, the switches could include a third switch coupled to the second input terminal and a second side of the resistor.
