A particulate profile control agent self-adaptive to a size of formation pore throat and a preparation method thereof include: raw materials and mass fraction for preparing a system including a main agent of 0.04&#x2dc;0.2%, a nucleating agent of 0.005&#x2dc;0.01%, a crosslinking agent of 0.002&#x2dc;0.04%, an additive of 0.005&#x2dc;0.01% and water. The preparation method includes: adding the main agent in proportion to the water and evenly mixing the mixture of the main agent and the water, and then adding the additive, the crosslinking agent and the nucleating agent in turn so as to form the profile control agent; pumping the profile control agent into the formation to be reacted at a reservoir temperature for a period of time to form colloidal particles on the spot for sealing off a high-permeability layer. The present disclosure is of easy operation and low cost, low initial viscosity and good injectivity.

A sub-threshold low-power and resistor-less reference circuit which is related to the field of reference circuit technology of analog circuit includes a negative-temperature-coefficient voltage generating circuit, a positive-temperature-coefficient voltage generating circuit and a current balancing circuit. The negative-temperature-coefficient voltage generating circuit generates a negative-temperature-coefficient voltage Vbased on the negative-temperature voltage characteristic of base-emitter PN junction of the bipolar tsansistor. On the other hand, the positive-temperature-coefficient voltage generating circuit generates a positive-temperature-coefficient voltage Vbased on the positive-temperature voltage characteristic of the NMOS transistor operating in a sub-threshold region. The current balancing circuit is configured to eliminate the error current caused due to the difference of the current mirror when the two voltages with different temperature characteristics are superposed to output a reference voltage.
