  • Patent number: 8315302
    Abstract: A modulator using a polynomial interpolator is described herein. In a simple circuit implementation of the modulator, coefficients of a representative polynomial are generated with interpolation filters in the polynomial interpolator. Crossing points may be identified for each sampling period by incorporating a virtual carrier waveform with the representative polynomial to generate a switching output control. Among other applications, the described modulator may be used in a Class-D amplifier. The described implementations may further confer benefits such as micro-power low voltage operation, low sampling rate, and low harmonic distortion.

  • Patent number: RE43818
    Abstract: A QFN integrated circuit is mounted on a leadframe having multiple lead lands and resin material encapsulates the integrated circuit leaving the lead lands exposed. Subsequently a sawing operation divides the lead lands into multiple leads, and the leadframe and resin material are partitioned to form packages. The pitch of the resultant leads is not limited by the pitch of the lead lands of the leadframe, so the leadframe can be of the relatively cheap generic leadframe variety, in which the pitch of the lead lands is higher than the desired pitch of the leads of the completed package. The sawing operation may further include reshaping the diepad area of the leadframe to produce heat sink fins, for improved heat dissipation. The proposed process is suitable both to produce packages including only a single integrated circuit, and also to produce multi-chip modules.
