MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202541133023 A) filed by Indian Institute Of Technology, Chennai, Tamil Nadu, on Dec. 29, 2025, for 'method and apparatus for current sensing in power regulation system.'
Inventor(s) include Qadeer Ahmad Khan.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure relates to apparatus and method for monitoring current in a power 5 regulator using two states of a PWM cycle. In the high state, a first comparator generates a difference voltage between the drain of a main transistor and a sense transistor. This voltage is processed by a digital accumulator to produce a first code, which a current DAC converts into a first current. In the low state, a second comparator generates a difference voltage between source voltages of a second sense transistor and another reference. This voltage is similarly 10 processed by a second digital accumulator to produce a second code, which the DAC converts into a second current. The method ensures accurate current monitoring across both PWM states for improved regulation and efficiency."
