Maynard, MA, United States, 2009/08/18 - Orchid Technologies Engineering and Consulting, designed a transconductance amplifer for detection of plaque build up in veins and arteries for their medical client.
Our client needed an amplifer system that could detect the smallest variations in florescent light levels inside the human body.
Detecting the florescence of foreign materials inside the human body is subject to a variety of competing technical challenges. Orchid met those challenges by designing a reliable, highly repeatable, and accurate transconductance amplifer.
Excited by a laser light source, this sensitive, tuned amplifier system can detect the smallest variation in florescent light levels inside the human body. Invasive data collection inside the human body is a demanding art. Detecting the florescence of foreign materials inside the human body is subject to a variety of competing technical challenges. The need for a reliable, highly repeatable, and accurate result is paramount.
The front-end amplifier is positioned on the end of a rotating detector mechanism. Slip rings carry power and the encoded data signals to stationary computer equipment. Selection of appropriate slip ring and data communications technology formed a large part of the custom design work performed by Orchid Technologies (orchid-tech.com). Custom encoded serial data communications protocols are used to pass data and control signals between stationary and rotating equipment.
“The design of high-speed sensitive transconductance amplifiers requires experience,” says, Paul Nickelsberg, President and CTO Orchid Technologies. “The amplifier is capable of detecting infra red light levels below-40dbm with a frequency response flat to 35KHz.” “We were able to use analog circuit modeling techniques, advanced on-the-bench prototyping and testing techniques, together with signal-source fixturing to design this high-speed transconductance amplifer.”
