Abstract

Aspects of the subject disclosure may include, for example, first and second operational amplifiers; and a differential pair of NPN transistors in a feedback path of the TLA configured to convert an input current signal into an output voltage signal, where a first emitter of a first NPN transistor of the pair of NPN transistors is connected to an inverting input of the first operational amplifier, and where a second emitter of a second NPN transistor of the pair of NPN transistors is connected to a non-inverting input of the second operational amplifier. Other embodiments are disclosed.
