Ah Siah Chua is a notable inventor based in Singapore, recognized for his contributions to the field of electrical engineering. With a total of 4 patents to his name, Chua has made significant advancements in power-on reset circuits and two-dimensional magnetic recording systems.

Latest Patents

Chua's latest patents include a power-on reset circuit that provides methods for generating a power-on reset signal. This circuit features a first branch that receives the power supply voltage and includes a first current generator. The first current generator is designed to produce a first current that has a positive relationship with the power supply voltage. Additionally, a second branch also receives the power supply voltage and contains a second current generator that produces a second current. The relationship between these two currents determines whether the power supply voltage exceeds a threshold voltage, thereby generating the power-on reset signal when the second current surpasses the first.

Another significant patent involves two-dimensional magnetic recording systems aimed at minimizing and accounting for inter-modulation of signals induced in adjacent read elements. This system comprises transmission lines, read elements, and differential amplifiers, with the read elements connected in series. Each read element is linked to a respective pair of transmission lines, and the differential amplifiers are configured to amplify the differential signals received from these transmission lines.
