Latest Patents

One of Amir's latest patents is a digital-to-analog converter utilizing pulse width modulation. This invention constructs a pulse width digital-to-analog converter that provides an output clock rate that is a multiple of the input sampling rate. In this embodiment, a latch is used to store an N-bit digital word representing the analog signal value to be generated. The most significant bits are stored in a counter that decrements its count in response to a clock signal. A plurality of least significant bits of the digital word stored in the latch are applied to a logic circuit. A ring counter indicates which section of the output signal is currently being generated. The transition of the output signal from a logical one to a logical zero is delayed when required, thereby maintaining or even increasing the resolution of the system.

Another significant patent is the multiplier/adder circuit. This invention features a uniquely designed switched capacitor multiplier/adder that also functions as a digital-to-analog converter in a single subcircuit. The multiplier/adder multiplies an analog voltage by a binary coefficient and sums this product with a second analog voltage in a single operation. This unique subcircuit significantly reduces the space requirements for constructing circuits, such as speech synthesis circuits utilizing linear predictive coding. The method minimizes error components in the synthesized speech signal due to voltage errors inherent in analog sample and hold circuits.
