Patent ID: 8067858

Claim:
An apparatus that receives a signal voltage, the apparatus comprising: a capacitive network that includes a first half cell connected in parallel with a second half cell, wherein the first half cell comprises a circuit with two or more voltage variable capacitors (VVCs) configured in anti-series in which a first VVC of said two or more VVCs with a same bias voltage orientation as the signal voltage associated with said apparatus assumes one capacitance and a second VVC of said two or more VVCs with an opposite bias voltage orientation as the signal voltage assumes another capacitance, and wherein the second half cell comprises a circuit with two or more VVCs configured in anti-series in which a third VVC of said two or more VVCs with the same bias voltage orientation as the signal voltage associated with said apparatus assumes the same values as said anti-oriented VVCs in said first half cell and a fourth VVC with the opposite bias voltage orientation as the signal voltage assumes the same values as said like-oriented VVCs in said first half cell; a first Direct Current (DC) feed connected between the first VVC and the second VVC; and a second DC feed connected between the third VVC and the fourth VVC, wherein said VVCs are voltage tunable dielectric capacitors, wherein values for the voltage tunable dielectric capacitors are selected based on reducing an error function over a desired range of bias and signal voltages as a function of a capacitance-voltage curve that numerically models the voltage tunable dielectric capacitors, and wherein the error function is based on a change in a net capacitance of the capacitive network.
