Latest Patents

One of Jie Lou's latest inventions is the "Accurate current mirror circuit in low voltage headroom applied to laser drivers." This invention provides an accurate current mirror circuit designed for common-anode laser drivers. It includes a reference current detection unit, a tail current source unit, and a control unit. The reference current detection unit generates a bias voltage and a reference voltage based on a reference current from the source. The tail current source unit utilizes the bias voltage to generate a mirror current. The control unit performs feedback regulation to ensure that the reference voltage and output voltage remain at the same level, thus preventing inaccuracies in current output due to control unit offsets in low voltage conditions.

Another significant patent is the "Multi-bit digitally controlled accurate current source circuit." This invention features a reference current detection unit, a voltage buffer unit, a digital logic control unit, a switch array unit, and a current source array unit. The reference current detection unit generates a first bias voltage, which is then buffered to create a buffer voltage. The digital logic control unit processes this buffer voltage to produce a digital control signal. The switch array unit uses this signal to control the on-off states of the current sources in the array. This design incorporates a voltage buffer to form a cascode current source, achieving an area-saving and accurate current source.
