Abstract
A digitally controlled capacitor includes a first set of N capacitors, wherein the first set has a first capacitance value and each of the M capacitors has a second capacitance value, and at least one second set of N capacitors. The second set has the first capacitance value and each of the N capacitors has a third capacitance value that is greater than the second capacitance value. M and N are integers greater than one and M is not equal to N.
