A transconductor and a proportional integral controller having the same are provided to improve a response characteristic of an integral by installing a capacitor unit between an output terminal of a transconductor and a ground. A transconductor includes an input unit(410), and an output unit(420). The input unit has two transistors having a different size. A main current of a large transistor of two transistors has first and second differential input terminals(411,412) which flow on a ground voltage source. The output unit sums and outputs the main current of a small transistor of two transistors which are included in each of the differential input terminals. The transistors included in the first and second differential input terminals are PMOS field effect transistors. A drain of small transistor of two transistors which are included in each of the differential input terminals is electrically coupled to the output unit. |
