摘要： A multiplier and a neural network synapse capable of removing nonlinear current using current mirror circuits. The multiplier produces a linear current by using MOS transistors operating in a nonsaturation region. The multiplier includes a first current mirror including a plurality of MOS transistors to form a first current and a second current mirror including a plurality of MOS transistors to form a second current, wherein the second current mirror is coupled in parallel to the first current mirror. As a result, the multiplier outputs an output current by subtracting a second current from said first current.

摘要： A multiplier capable of removing nonlinear current using current mirror circuits. The multiplier uses MOSFET and BJT devices by the BiCOMS processes. The multiplier includes three current mirror circuits. A first current mirror includes a BJT Q.sub.3 and a BJT Q.sub.5 and also the BJT Q.sub.3 is coupled in series to the n-channel MOSFET M1 between the voltage V.sub.1 and a ground voltage level. A second current mirror includes a BJT Q.sub.7 and a BJT Q.sub.8. A third current mirror includes a BJT Q.sub.4 and a BJT Q.sub.6. Consequently, input voltage signals V.sub.1 and V.sub.dc applied to the n-channel MOSFETs M1 determine the current I.sub.1 and input voltage signals V.sub.1 and V.sub.2 applied to the n-channel MOSFET M2 determine the current I.sub.2.
