Latest Patents

One of Chun-An Tang's latest patents is titled "Method and circuit for trimming an internal oscillator of a USB device according to a counting number between a first and second clock count value." This invention involves a circuit and method that allows for the trimming of an internal oscillator in a USB device. It generates a clock signal as a frequency source and detects the end of a packet from an input data stream to initialize a counter. The invention identifies a token packet in the data stream to detect a start of frame token packet, enabling the counter to carry out clock counting on the clock signal. This process ultimately helps in obtaining a count value, which is then compared with a reference value to determine a trimming code for adjusting the clock frequency of the internal oscillator.

Another significant patent by Tang is the "On-system programmable and off-system programmable chip." This invention comprises a control circuit connected to both an on-system programmable nonvolatile memory and an off-system programmable nonvolatile memory. It also includes a pumping circuit connected to the on-system programmable nonvolatile memory. In the programming mode of the chip, external programming voltages are provided for the off-system programmable nonvolatile memory. In the operation mode, the pumping circuit generates internal programming voltages for the on-system programmable nonvolatile memory.
