Devices, systems, and methods employ an implant that is sized and configured to attach in, on, or near the annulus of a dysfunctional heart valve. By digitally generating a sinusoid that is frequency locked to a two-state input reference signal using a high rate internal clock, a hardware-efficient BTSC pilot signal generator is provided with good acquisition and tracking performance. In a first output mode, the output control circuit controls one of the first conductive transistor and the second conductive transistor to go to off and controls the other transistor to go to onoff, whereas in a second output mode, the output control circuit controls the first conductive transistor to go to on and the second conductive transistor to go to off or vice versa. Depending on a clinical situation, electrodes of various size and configuration are used. For example, the particles may be formed of a functionalized polyester graft copolymer consisting of a linear -hydroxy-acid polyester backbone having at least one amino acid group incorporated therein and at least one poly side chain extending from an amino acid group in the polyester backbone. The device and the manufacturing method deliver a power SiC MOSFET with increased frequency of operation and reduced switching losses.
