Abstract
Official abstract text for this publication.
The present invention relates to a voltage bandgap buffer apparatus. This apparatus includes a voltage processing module to produce a bandgap buffer voltage in response to an input voltage and a feedback signal and a symmetry circuit. This symmetry circuit is coupled to the voltage processing module for producing the feedback signal and for regulating the feedback signal in response to the input voltage.
First claim
Opening claim text (preview).
What is claimed is: 1. A bandgap buffer for providing a bandgap buffer voltage to a chip, comprising: an operational amplifier having an output terminal, a first input terminal, and a second input terminal receiving an input voltage; a first transistor having a control terminal connected to the output terminal and a first terminal connected to the chip power source so as to provide the bandgap buffer voltage; and a switching array including: (N+1) first resistors connected in…
