A multi-input transistor circuit including a plurality of input MOS transistors having gates each serving as an analog voltage input terminal, operating in a non-saturation area and connected in parallel; and circuit for providing a constant drain/source voltage for each of the input MOS transistors, and having a current output point. A multi-input transconductance circuit including first and second MOS transistor groups having gates serving as first and second analog voltage input terminals, respectively, operating in a non-saturation area and connected in parallel; and a circuit for providing constant drain/source voltage for the transistors in each group and connected to a common source connecting point of each of the first and second MOS transistor groups, and having first and second current output terminals. The multi-input transistor and the multi-input transconductance circuit exhibit input-to-output linearity, have a wide dynamic range and are equivalent to an n-gate transistor.
