Biography Geoffrey Weil
Geoffrey Weil is recognized internationally for his skills as a high speed analog design engineer. He has focused on high speed, high voltage applications through most of his career. He attended Harvard University in Physics and Mathematics before entering the field of professional engineering.
At MIT he worked as a member of the technical staff for the Rai Weiss group. He designed, built and tested power supplies, signal conditioning and data acquisition components of the balloon borne experiment to measure the cosmic microwave background. During this time, he also participated in a search for gravity waves and was responsible for data acquisition, control and signal conditioning.
He joined Hyperion Industries of MA as an electronics engineer. He gained experience there designing custom switching power supplies. Notably, he developed the technology for stacking series MOS FETs to achieve a composite switching component with higher operating voltage than individual FETs.
He worked at KeyTek Instrument Corporation of MA, joining as an engineer and later was promoted to Director of Research and Development. The company designs and manufactures ESD simulators including ultra-fast CDM simulators which offer sub-nanosecond rise time and multi kV swings. He patented the technique of HV switching with gas-filled relays. He was responsible for the MiniZap and the ZapMaster development, both of which remain the standards of the electronics industry. He developed a 5 kV fast switching solid state switch capable of switching 120 A using stacked MOS FET technology. This component became the heart of an electrical fast transient simulator for KeyTek.
After KeyTek, Mr. Weil worked for Datacom in WA, an Ethernet cable tester manufacturer. He was director of Advanced Technology Products. Among his accomplishments, he designed a 350 MHz hand-held cable tester.
He worked for Comtest Engineering B.V. in the Netherlands as an R&D Engineer. Notably, he designed a low cost lightning simulator using SCRs as the switching element, a multi- GHz bandwidth reference E-Field source for antenna calibration and an RF fiber-optic analog transmitter with a 3 kHz-2 GHz bandwidth used for inserting signals into an anechoic chamber for EMI testing.
In the past 5 years he has worked on a variety of analog projects under the name Anodyne Research, having designed an non-contacting electrostatic voltmeter, an ESD-induced EMI detector, a Charged Plate Monitor, an ESD Target current viewing detector and other ESD related projects.
Although most electronics today employs solid state devices, Mr. Weil still has the skill to work with electron tubes both of the gaseous discharge variety and the linear type.
Mr. Weil holds 4 patents in electronic engineering technology.
