Abstract: Disclosed herein is a hybrid ventilation apparatus capable of both natural and forced ventilation. In the case of a natural ventilation mode, a worm gear is rotated in a normal direction by drive force of a drive unit under control of a control unit so that a pressing member engages with a rotation guide protrusion and rotates a damper, thus opening a flow passage, and then the worm gear is reversely rotated by drive force of the drive unit to return the pressing member to its original position, thus allowing a user to rotate a roller upwards and downwards and rotate the damper so that the degree of opening of the flow passage can be adjusted. Thereby, rapid inflow of outdoor air can be blocked, and a cold graft phenomenon, in which the temperature of indoor air rapidly drops, can be prevented.

Abstract: A circuit and method for a bandgap voltage reference operating at 1 volt or below is disclosed, wherein the operational amplifier (A1) drives resistors (R2, R3) only so that both the flicker noise contribution and the process sensitivity due to the conventional metal oxide semiconductor (MOS) devices used as a current mirror within the proportional-to-absolute-temperature (PTAT) loop are eliminated. Two symmetric resistive divider pairs formed by (R1A/R1B, R2A/R2B) are inserted to scale down both the base-emitter voltages (VEB1, VEB2) of bipolar transistors (Q1, Q2) and the PTAT current (IPTAT) so that an output reference voltage (VREF) becomes scalable. Proper bias currents through transistors (M3, M4), which are used to bias (Q1, Q2) and (R1A/R1B, R2A/R2B) respectively, are produced by an additional V-I converter (319) using VREF itself, resulting in a final process, voltage and temperature (PVT) insensitive output reference voltage.
