Title: Manop Thamsirianunt: Innovator in Frequency Control Technologies

Introduction

Manop Thamsirianunt is a notable inventor based in Fremont, California. He has made significant contributions to the field of frequency control technologies, holding two patents that showcase his innovative approach to electronic design.

Latest Patents

One of his latest patents is the "Automatic Frequency Rate Switch." This invention provides a method and apparatus for automatically determining the protocol being used from the frequency of an applied clock without the need for a separate pin or switch or a second external clock. The clock's frequency is identified when it falls into a set range targeted by the apparatus. Based on the detected frequency, a mode select signal is generated, allowing the chip to configure to the appropriate frequency and other unique configuration parameters. In one embodiment, the invention generates a ramp signal triggered by the external clock, which is simultaneously applied to a counter. When the ramp signal reaches a reference voltage, the count of the counter is compared to at least one threshold to determine the corresponding frequency. The chip is then configured according to the indicated communication mode or protocol.

Another significant patent is the "Universal Duty Cycle Adjustment Circuit." This invention is a duty cycle control circuit that consumes lower power and occupies a smaller silicon area, while also being less susceptible to noise or jitter. In one embodiment, the invention includes a divide-by-two circuit that is edge-triggered, generating a signal at its output with half the frequency of the input signal but with a 50% duty cycle. This circuit is followed by a frequency restore circuit that restores the original frequency of the input signal while regulating its duty cycle at about 50% or any other desired level.
