Title:
DIGITALLY OPERATING ANALOG BUFFER AMPLIFIER
Document Type and Number:
Japanese Patent JP3286300
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a digitally operating analog buffer amplifier which is small in circuit scale, fast and consumes small power without generating offset voltage.
SOLUTION: The digitally operating analog buffer amplifier is comprised of a comparator CMPT, a level shifter LVSF and two switches SW, and configured such that when an output voltage approaches a proximity value of an input voltage (set voltage value), an input terminal IN and an output terminal OUT are short circuited by the switch SW to equalize the output voltage to the input voltage for preventing the occurrence of offset voltage, thereby it is possible to complete its operation while operating digitally and to reduce power consumption.
