Latest Patents

Zhuoyuan Li's latest patents include two notable inventions. The first is an "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 uses this bias voltage to generate a mirror current. The control unit then regulates the bias voltage based on the reference voltage and the output voltage corresponding to the mirror current. This design effectively locks the reference voltage and output voltage at the same level, thus preventing inaccuracies in current output due to control unit offsets in low voltage conditions.

The second patent is a "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 based on a reference current. The voltage buffer unit then produces a buffer voltage from this bias voltage. The digital logic control unit generates a digital control signal based on the buffer voltage. The switch array unit uses this signal to create on-off signals, which the current source array unit responds to in order to control the activation of the current sources. This invention achieves an area-saving accurate current source by incorporating a single voltage buffer to form a cascode current source.
