摘要： A dual supply level shifter circuit includes a switching circuit and a set of level shifter circuits coupled to the switching circuit. The switching circuit includes a first set of coupled transistors, wherein the supply switching circuit is coupled to a first supply source that is configured to provide a first power supply voltage and is coupled to a second supply source that is configured to provide a second power supply voltage. The set of level shifter circuits includes a second set of coupled transistors, wherein the set of level shifter circuits is configured to receive a voltage input signal at an input node from a first circuit and to supply to an output node of the dual supply level shifter circuit an output signal having a value that is a highest voltage value between the first power supply voltage and the second power supply voltage.

摘要： An analog-to-digital (A/D) converter suitable for use with redundant signed digit (RSD) coverter stages is provided with an out-of-range (OOR) detection circuit. If an out-of-range input signal is detected, the detection circuit identifies the OOR condition so that the converter can take remedial action. Examples of remedial action may include adjusting the gain of one or more converter stages, adjusting the analog input signal provided to one or more converter stages, and/or adjusting the digital output of the converter to reflect the OOR condition. The ORR detection circuit may receive its input from a converter stage that is distinct from the stage providing the most significant bit (MSB) of the digital output to preserve the resolution of the most significant bit.
