Abstract
Disclosed is a transconductor including: first and second transistors each having first and second gates, the first and second gates being independently controlled, differential voltage input being supplied between the one first gate and the other first gate, the one source and the other source being connected, a first control voltage being commonly given to both of the second gates, and the drains being differential current output terminals; third and fourth transistors each having the same connection as the first and second transistors, each of the one drain and the other drain being connected with either of the one drain and the other drain of the first and the second transistors so that polarities are opposite to each other; and a current source connected with both of the sources of the first and the second transistors and both of the sources of the third and the fourth transistors.
