Latest Patents

Tapani holds a patent titled "System and method of scaling error signals of caseload second order." This invention relates to a method of cascading two or more sigma-delta modulators. It involves applying an error signal that represents the quantization error of a preceding modulator to a subsequent modulator in the cascade. The quantized error signal is then differentiated and subtracted from the quantized output signal of the preceding modulator. To enhance the performance of the cascade, the method scales the error signal before the subsequent modulator by a first factor smaller than 1. The quantized error signal is scaled by a second factor that is substantially equal to the inverse of the first factor before being subtracted from the quantized output signal of the preceding modulator. Tapani has 1 patent to his name.
