Abstract: A comparator capable of realizing a stabilized output signal is disclosed. A latch type comparator senses a difference of input signals in the positive edge of a clock signal and forms a first set signal and a first reset signal. A buffer part is included in order to stabilize the output level of the formed first set signal and first reset signal and enhance the drive efficiency of a device. A second set signal and a second reset signal are formed through a buffering operation and are inputted to a latch part with an expended swing width. A stabilized output range is secured by the forementioned. [Reference numerals] (100) Latch type comparator;(200) Buffer part;(300) Latch part

Abstract: Disclosed is a reference voltage generator which forms a constant output voltage even in a temperature change. The reference voltage generator has a reference voltage generation part which generates a reference voltage by the generation of a reference current and a start-up control part which induces the start-up operation of the reference voltage generation part. The start-up control part is connected to a temperature correction part which induces the generation of a constant reference current even in a temperature change. Especially, the start-up control part receives both terminal voltages of a detection resistance which is connected in series to the bipolar transistor of the temperature correction part and induces the start-up operation of the reference voltage generation part based on a received signal. Therefore, the start-up operation can be carried out by accurately detecting the operation condition of the temperature correction part which performs a temperature correction operation.
