Abstract
Methods and systems for a low input voltage low impedance termination stage for current inputs may include, in a semiconductor die, generating an output current proportional to an input signal, where the output current is generated by an output stage that may include a pair of input cascode transistors and at least one pair of stacked output transistors. A source-follower feedback path for the input cascode transistors may include a feedback transistor with its gate terminal coupled to a drain terminal of a first of the input cascode transistors, a drain of the feedback transistor coupled to a supply voltage, and a source terminal of the feedback transistor coupled to a current source that is coupled to ground. A current source may be coupled to the drain of the first of the input cascode transistors. The supply voltage may be coupled to the stacked output transistors via a load resistor.
