Abstract
A referential amplifier device includes an input port configured to be electrically coupled to a source to receive an input signal from the source at an input voltage level. A first current path system is coupled to the input port and comprises a first transconductor device, a third transconductor device, a first resistor device, and a second resistor device. A second current path system is in parallel with the first current path system and comprises a second transconductor device and a fourth transconductor device. A current level in the second transconductor device is set equal to a current level in the first transconductor device, and a current level in the second transconductor device is set equal to a current level in the fourth transconductor device. An output port is coupled to the second current path system and configured to provide an output voltage based on a difference between the input voltage level and a threshold voltage level for the referential amplifier device. A method of making the referential amplifier device is also disclosed.
