摘要

#CMT# #/CMT# The device has positive and zero temperature coefficient current generators (11, 12), and an adjustable temperature coefficient current generator (14) that generates and delivers adjustable temperature coefficient current (I-ATC) by amplifying positive and zero temperature coefficient currents (I-PTC, I-ZTC) for A and B times and by adding the amplified currents. A temperature coefficient of the current is modified in a selective manner by adjusting values of A and B. #CMT#USE : #/CMT# Device for generating polarization current. #CMT#ADVANTAGE : #/CMT# The device permits to generate different polarization current having set of temperature coefficient in which different characteristics changes are compensated in different circuits such as analog circuit or radiofrequency circuit in a stable manner, where the characteristics changes are take place based on temperature. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic block representation of a polarization current generating device with an adjustable temperature coefficient.'(Drawing includes non-English language text)' I-ATC : Adjustable temperature coefficient current I-PTC : Positive temperature coefficient current I-ZTC : Zero temperature coefficient current 11 : Positive temperature coefficient current generator 12 : Zero temperature coefficient current generator 13 : Amplifier 14 : Adjustable temperature coefficient current generator 122 : Voltage-current conversion unit.
