PURPOSE:To realize a MOS four-quadrant multiplier which is formed in a semiconductor integrated circuit with a linear input voltage range. CONSTITUTION:The positive phase of a second input signal V2 is inputted to one of two-quadrant multipliers with the first input signal V1 as a common input and an opposite phase V2' is inputted to the other two-quadrant multiplier. The four two-quadrant multipliers are constituted as shown in the figure and a result with good linearity is outputted in accordance with the polarity of the two signal inputs. |
