A resistorless CMOS low power voltage reference circuit is provided. The start-up circuit is used to prevent the circuit to stay in the zero state and stop working when the circuit gets out of the zero state. The self-biased Vgenerating circuit generate the voltage Vwhich has positive temperature coefficient. The square-law current generating circuit generates a square-law current which is proportional to &#x3bc;Tthrough the V. Finally, the reference voltage Vis obtained by introducing the square-law current into the reference voltage output circuit. The reference voltage Vof this application can realize approximative zero temperature coefficient in the temperature range of &#x2212;40&#xb0; C.100&#xb0; C. This application improves temperature characteristic which may be poorer due to temperature nonlinearity of carrier mobility based on the traditional subthreshold reference. This application can reduce the power consumption from &#x3bc;W level to nW level and realize low power consumption.

A low-dropout regulator with super transconductance structure relates to the field of power management technology. The super-transconductance structure refers to the circuit structure in which the voltage signal is converted into a current signal and amplified with a high magnification. The error amplifier EA in the present invention uses the super transconductance structure. The differential input pair of the error amplifier EA samples the difference between the feedback voltage Vand the dynamic reference voltage V. The difference is converted into a small signal current, which goes through a first-stage of current mirror to be amplified by K, and through a second-stage of current mirror to be amplified by K. The amplified signal is used to regulate the gate of the adjustment transistor MP. The error amplifier EA with the super transconductance structure is used to expand the bandwidth of the error amplifier EA.
