A CMOS voltage-to-current converter in weak inversion is presented in this Letter. It can operate for low supply voltage and its power consumption is also low. As the input voltage varies from -0.15 V to 0.15 V, the measured maximum linearity error for the proposed voltage-to-current converter, is about 3.35%. Its power consumption is only 26 µW under the supply voltage of 2 V. The proposed voltage-to-current converter has been fabricated in a 0.5 µm N-well CMOS 2P2M process. The proposed circuit is expected to be useful in analog signal processing applications.
