Full CMOS reference circuit

Abstract

The invention discloses a full CMOS reference circuit, comprising a starting circuit used for starting a reference circuit, and a core reference circuit adopting a self-bias structure. According to the full CMOS reference circuit, the precision of the generated reference voltage is very high, the influence of the temperature is small, and the area of the whole circuit is very small because no resistor is adopted in the whole circuit.

Description

technical field [0001] The invention relates to the field of reference voltage circuits, in particular to an all-CMOS reference circuit. Background technique [0002] In the Internet of Things, EEPROM and most wireless communication applications, the relevant receiving circuits or transmitting circuits require low power consumption, so a reference circuit that can generate low power consumption is very critical and necessary for the entire application . As an important part of the analog circuit, the reference circuit generally needs to work normally in a wide temperature range. Therefore, not only low power consumption is required, but also stable performance and good temperature characteristics are required. The traditional method can be designed with a bandgap reference circuit, but its power consumption is at the microwatt level, which does not belong to the low-power design category. Contents of the invention [0003] In order to overcome the above-mentioned problem...
