Abstract: A low-dropout voltage system comprising a current supply (320) with a transistor circuitry (MP1˜MP5, MN1˜MN5), a mode switch capacitor (340), and a decoupling capacitor (350), wherein the mode switch capacitor (340) facilitates the low-drop voltage system to swiftly transition from a low mode with a minimal to no transient current output to a high mode with a transient current of about 6 mA by dynamically biasing the transistor circuitry (MP3˜MP5, MN1˜MN5) while limiting a voltage or current draw from an external power source.

Abstract: An encoding and transmitting system for a digital isolator system includes a transmitter for transmitting combined edge indicator signals through an isolation barrier, an encoder for generating the combined edge indicator signals based on first and second signals, a refresh clock generator for generating a refresh clock signal based on the first signal, and a refresh edge generator for masking at least a portion of the refresh clock signal, such that the portion of the refresh clock signal is not reflected in the second signal. The isolation barrier of the digital isolator system may be a capacitive isolation barrier for galvanically isolating a receiver from the transmitter. If desired, the refresh edge generator may include a refresh mask generator, one or more logic gates, and a glitch filter. A method of operating a digital isolator system is also described.
