Temperature insensitive current source
摘要:
A circuit is presented which can produce a temperature insensitive, constant current value. The constant current source comprises transistor pairs which mirror a temperature dependent current into a node along with another temperature dependent current. The node thereby receives two temperature dependent currents, wherein one is inversely dependent to that of the other. More specifically, one current increases as temperature increases, whereas the other current decreases as temperature increases. The two currents may thereby be construed to offset one another such that the output of a common node produces a current output which does not change with either an increase or decrease in temperature imputted upon the current source component.
