Abstract

See full text

An integrated-circuit, continuous-time, sigma-delta analog-to-digital converter has a single-ended analog input, a converter reference input, and a ground connection. The converter has a resistor-capacitor integrator arranged to receive the single-ended analog input. The integrator comprises a differential amplifier. The converter also has a clocked comparator connected to an output from the integrator, and circuitry arranged so that reference inputs to the amplifier and to the comparator can be maintained at a common voltage derived from the converter reference input.
