Patent ID: 8760220

Claim:
A beta enhancement circuit for a voltage source, the beta enhancement circuit comprising: a voltage regulation circuit coupled to a first voltage potential, wherein the voltage regulation circuit is configured to generate an output voltage that is based on a beta value, and wherein the output voltage varies from a desired output voltage based on an error caused by the beta value, the beta value being associated with a common-emitter current gain of the voltage regulation circuit; and a resistive circuit coupled between (i) a control terminal of the voltage regulation circuit and (ii) a second voltage potential, the resistive circuit having a resistance value that is configured to minimize the variation of the output voltage from the desired output voltage by reducing or eliminating the error caused by the beta value, wherein the error caused by the beta value includes a first order error and higher order errors, and wherein: the output voltage varies from the desired output voltage based on the first order error and the higher order errors; and the resistance value of the resistive circuit is configured to reduce or eliminate the first order error while preserving the higher order errors.
