Layout for capacitor pair with high capacitance matching
An integrated circuit device includes a capacitor array, which includes unit capacitors arranged in rows and columns, wherein each unit capacitor is formed of two electrically insulated capacitor plates. The unit capacitors include at least one first unit capacitor in each row and in each column of the capacitor array; the at least one first unit capacitor being interconnected, wherein each row of the capacitor array comprises a same number of the at least one first unit capacitors as other rows and columns have, and wherein each column of the capacitor array comprises a same number of the at least one first unit capacitors as other rows and columns have. The unit capacitors further include at least one second unit capacitor in each row and in each column of the capacitor array, wherein the at least one second unit is interconnected and evenly distributed throughout the array.
