Latest Patents

One of Ju-An Chiang's latest patents is a temperature-sensing circuit and operating method. This invention includes a search-control circuit, a voltage-reference circuit, a CTAT (complementary to absolute temperature) circuit, a digital-to-analog converter (DAC) circuit, a comparison circuit, and an SAR (successive approximation register) circuit. The search-control circuit generates a reference-voltage selection signal based on multiple control signals. The voltage-reference circuit selects a first reference voltage from various candidate reference voltages according to this selection signal and provides a second reference voltage. The CTAT circuit converts the second reference voltage into a first comparison voltage, while the DAC circuit converts the first reference voltage into a second comparison voltage. The comparison circuit then compares these two voltages to generate a comparison-result signal, which the SAR control circuit uses to output each bit of a temperature-segment signal corresponding to the operating temperature.

Another notable invention is a digital-to-analog converter that comprises an amplifier, a voltage relaxation circuit, a base current source, a first weighting current source, and at least one second weighting current source. The amplifier receives a reference voltage and a feedback voltage, generating an output voltage based on these inputs. The base current source is connected to the amplifier's output through the voltage relaxation circuit, allowing it to produce an adjustable base current. The first weighting current source generates an adjustable first weighting current based on the input data, while the second weighting current source produces at least one second weighting current according to additional bits of input data.
