Latest Patents

One of his latest patents is a signal processor designed for 1-bit signals. This processor features a fifth order Delta-Sigma Modulator (DSM) that receives a 1-bit signal and produces a processed 1-bit signal through a quantizer. The quantizer operates on a p-bit signal derived from five signal integration stages. Each stage includes a first 1-bit multiplier connected to the input, a second 1-bit multiplier linked to the output, an adder that sums the outputs of the coefficient multipliers, and an integrator that integrates the output of the adder. The final stage consists of a coefficient multiplier and an adder that sums the output of the coefficient multiplier with the output of the preceding integration stage's integrator. The coefficients are selected to ensure overall attenuation of the input signal and the quantization noise generated by the quantizer. This reduction in quantization noise allows multiple DSMs to be connected in series without accumulating excess noise, which could jeopardize stability.

Another significant patent involves a signal processing system that employs a differentially quantized digital signal. This digital signal consists of two bits representing three values, where one value is zero, and the other two represent positive and negative values, respectively. This innovative approach enhances the efficiency of signal processing systems.
