  • High accuracy voltage references
    Patent number: 10088861
    Abstract: Two transistors are connected between a power source and separate current references. The base of the first transistor is connected to a bias voltage, and the base of the second transistor is connected to the output of a differential amplifier. The amplifier inputs are connected to the nodes where the transistors are connected to the current references. The transistors and the current references may be of different sizes, such that the output voltage of the amplifier is a function of temperature and of the product of the ratios of the transistors and the current references. A number of switches may be employed such that, in alternative modes of operation, the amplifier is used to buffer the bias voltage, the offset of the amplifier, the output of the first transistor, and/or a stored sample of the temperature output voltage, which are combined to arrive at an adjusted temperature reading.
