Patent number: 8193854Abstract: A bandgap reference circuit has trimming-up resistors and trimming-down resistors for bi-directional trimming. PNP transistors have base and collectors grounded and emitters connected to parallel resistors. A difference resistor drives an inverting input of an op amp that drives a transistor that generates the bandgap reference voltage Vbg. A sensing resistor connects Vbg to a splitting node that connects to the non-inverting input through a first parallel resistor. The splitting node also connects through a second parallel resistor to the inverting input. Fuses or switches enable the trimming-up and trimming-down resistors. The trimming-up resistors are in series with the sensing resistor and the trimming-down resistors are in series with an output resistor that connects Vbg to reference voltage Vref. The circuit can be designed for a more typical process since bi-directional trimming allows Vref to be raised or lowered. Many circuits need no trimming when targeted for the typical process.Type: GrantFiled: January 4, 2010Date of Patent: June 5, 2012Assignee: Hong Kong Applied Science and Technology Research Institute Company, Ltd.Inventors: Xiao Fei Kuang, Kam Chuen Wan, Kwai Chi Chan, Yat To (William) Wong, Kwok Kuen (David) Kwong
