Latest Patents
Karasawa holds a patent for a "Method and circuit for producing trimmed voltage using D/A converter circuit." This invention focuses on trimming voltage by disconnecting a fuse connected in parallel to a feedback resistor of an amplifier circuit. The method addresses the variations in voltage value caused by remaining resistance components. The voltage generator circuit incorporates a D/A converter circuit of an R-2R ladder resistor network type. It features a series of switch circuits that correspond to each bit, allowing for the setting of a digital value. Each switch circuit is equipped with a fuse that provides a fixed voltage value, which can be disconnected to fix the voltage to an inverted initial value. The setting circuit controls the switching operation, simulating the electrical state of a fuse being disconnected before the actual disconnection occurs.
