Latest Patents

One of Chen's latest patents is a linear voltage regulator with improved responses to source transients. This innovative device features a regulating transistor that receives an input voltage source and provides an output voltage. The control electrode of the regulating transistor is managed by an error amplifying circuit, which compares a feedback signal of the output voltage with a reference voltage. An event detecting circuit is integrated to monitor the input voltage source for transient occurrences. Upon detecting a transient event, an enable controlling circuit generates a signal to determine the effective operation time of a voltage clamping circuit. This design ensures that the potential difference between the first channel electrode and the control electrode remains within a predetermined clamp voltage, preventing drastic changes in the operation of the regulating transistor.

Another notable patent is a reverse current preventing circuit with automatic correction of reference. This invention involves a synchronous switching voltage converter that includes a first switch, a second switch, and an inductor connected to a switch node. The reverse current preventing circuit comprises a fixed reference current source, a correcting circuit, a variable reference current generating circuit, and a comparing circuit. The correcting circuit generates a signal based on the comparison between the inductor current and the fixed reference current source. The variable reference current generating circuit adjusts the variable reference current signal according to the correcting signal. The comparing circuit then applies a preventing signal to the second switch, effectively turning it off when necessary.
