“…In 2015, Ahmad Hassan [8] implemented a wide temperature full MOS voltage reference using the temperature compensation principle of linear difference of MOSFET gate source voltage operating in the subthreshold region. In 2016, C.Jhon A.Gomez [9] proposed that the temperature characteristic relationship between threshold voltage and thermal voltage could be used for temperature compensation. In recent years, the research on the MOS voltage reference source is not limited to the realization of a new theoretical method, but to improve and optimize the various performance of the circuit [10,11].…”

Voltage mode band-gap reference source and current mode band-gap reference source is the basic unit of integrated circuit, which plays an important role in some circuit systems such as low-voltage linear regulator, power control chip and analog-to-digital/analog-to-digital converter. Band-gap reference circuit is divided into voltage mode band-gap reference circuit and current mode band-gap reference circuit, and their basic principles and optimization methods are different. The voltage mode bandgap reference voltage is generated by superimposing voltages with positive and negative temperature coefficients, thereby producing a low-temperature related factor. In contrast, the current mode bandgap reference generates a reference voltage by superimposing currents with positive and negative temperature coefficients, requiring appropriate resistance matching and compensation. This paper analyzes the basic principles of the above two band-gap reference circuits, analyzes the temperature characteristics and mismatch sources of them, compares the research results including the implementation mode, temperature characteristics, application range and optimization scheme of the two, and looks forward to the future development prospect of both types of circuits.
