Latest Patents
One of his latest patents is an RFID reader and circuit and method for echo cancellation thereof. This invention provides an echo cancellation circuit for an RFID reader, which includes a gain calculator, a gain adjustment circuit, and a subtraction circuit. The gain calculator utilizes an adaptive algorithm to provide a complex gain value based on a carrier signal and a received signal. The gain adjustment circuit multiplies the carrier signal by this complex gain value, while the subtraction circuit subtracts the output of the gain adjustment circuit from the received signal, resulting in an output signal that effectively cancels echoes.
Another significant patent is a printed circuit unit based on organic transistors. This unit comprises an input signal circuit, a load circuit, and a level shifter. The input signal circuit features N serially connected organic transistors. When one of these transistors is cut off, the signal input circuit is also cut off, ensuring that the circuit maintains a correct voltage level. The level shifter circuit includes an organic transistor that receives the input signal and can also function as a load to enhance the gain of the level shifter.
