Abstract: The amplifier circuit includes a pair of differential input stages coupled to an output stage where both a selected input stage and an unselected input stage are active with one of either a differential input signal or a reference voltage. A switching network couples a first input differential signal to a first differential input stage and a reference voltage to a second differential input stage when an amplifier input signal is less than a threshold voltage. The switching circuit also couples the second input differential signal to the second differential input stage and the reference voltage to the first differential input stage when the amplifier input signal is greater than the threshold signal.

Abstract: A delta-Vbe based bandgap reference voltage circuit generates a temperature stable reference voltage. First and second paths of the circuit each include a respective transistor coupled in series with a resistance. The collector current density of the transistor in first path is lower than the collector current density of transistor in the other path. A control path is used to generate a 2Vbe voltage that is coupled to the base nodes of the resistors in each path. A resistance that is coupled between a common node of a first end of the two paths and a circuit ground node. The circuit current is controlled by this resistance and a voltage drop of 2ΔVbe is across the resistance. The output reference voltage of the circuit is 2(Vbe+ΔVbe) when stack resistors in each path are used.

Abstract: Techniques are provided for an integrated circuit, current loop interface that can receive and extract a high-frequency digital communication signal from a low-frequency analog current signal using a complex impedance circuit. The complex impedance circuit can allow for low input impedance at the lower frequencies of the analog current signal and high input impedance at the higher frequencies of the digital communication signal.
