Abstract
A reference voltage generation circuit includes: a bandgap reference circuit, generating a plurality of initial currents with different temperature coefficients; a base voltage generation circuit, combining the initial current into a combined current, and converting the combined current into one or more base voltages; a bias current source circuit, generating one or more bias currents based on at least one of the initial currents; and one or more regulating output circuit, each converting a respective one of the one or more bias currents into an increment voltage and adding the increment voltage to the base voltage to generate a respective output voltage. Each output voltage may have its respective temperature coefficient.
