Abstract
An analog-to-digital converter based on the Bernoulli map's iterative principle, made by discrete, hybrid, mixed components, or on an integrated circuit, utilizes a single main loop circuit in which the analog signal cycles N times.
Claims15
A programmable analog-to-digital converter utilizing Bernoulli map's iterative principle comprising:
- a main loop circuit comprising
- an analog memory whose output is connected to a buffer,
- an output of said buffer being connected to a factor-2 amplifier input and a comparator input,
- said factor-2 amplifier being connected in parallel with said comparator and a normalization element,
- an output of said comparator being provided as an input to said normalization element,
- said factor-2 amplifier and said normalization element each providing an input to a subtractor, said subtractor including an input to said analog memory;
- an input enable line and an input voltage signal line connected to said analog memory;
- a binary serial output line provided by said comparator,
- wherein an analog signal to be converted to a digital signal is inputted on said input voltage signal line and said main loop circuit cycles the analog signal to provide an N bit output at said binary serial output line.
