Abstract
A capacitor bank adapted to provide a variable capacitance to an electronic circuit is provided. The capacitor bank has at least a most significant bit and a least significant bit and includes a first capacitor cell having a first capacitance value and disposed between a first node and a second node, thereby forming the most significant bit. The capacitor bank also includes a second capacitor cell having a second capacitance value and disposed between the first node and the second node, thereby forming the least significant bit. The second capacitance value is less than the first capacitance value. Additionally, the second capacitor cell includes a first T-network capacitor unit in electrical communication with a source of a transistor and a second T-network capacitor unit in electrical communication with a drain of the transistor.
