Latest Patents

One of Arnab Dutta's latest patents is a power-on reset system for a secondary supply domain. This innovative circuit provides startup current and a reference voltage for a comparator, which compares the reference voltage with a primary supply voltage to develop a bias current. The design includes a VGS loop that mirrors the bias current to create the reference voltage. When the comparator switches, the bias current operates at a low quiescent current level. Additionally, a level shift and isolation circuit isolates a primary POR signal from the secondary domain. The delay circuit senses the ramping of the secondary supply voltage and provides a delayed secondary POR signal after the secondary supply voltage reaches a predetermined threshold, further controlling the reset state.

Another significant patent involves an apparatus with electronic circuitry designed to reduce leakage current. This apparatus includes an integrated circuit (IC) with complementary metal oxide semiconductor (CMOS) circuitry. The IC features a pull-up network connected to a supply voltage and at least one input signal. A first metal oxide semiconductor (MOS) transistor is coupled to the pull-up network and a first bias voltage to minimize gate-induced drain leakage (GIDL) current in the CMOS circuitry.
