Marek is a Senior Analog Applications Engineer on Texas Instruments Precision Analog Linear team. Prior to its acquisition by Texas Instruments in 2001, he had worked for ten years at Burr-Brown Corp as an analog IC design engineer introducing over twenty new products. Following acquisition, he was an IC design manager in charge of development of series and shunt voltage references as well as precision instrumentation amplifies. In his current position as an application engineer, co-invented Green-Lis op amp, behavioral macro-model architecture - the state-of-the-art PSpice based simulation tool that meticulously simulates the exact performance of over twenty datasheet analog parameters - it’s a highly innovative macro-model topology that is unparalleled in the industry. His current focus is to provide training at technical summits as well as lecture worldwide at customers' Tech Day events on variety of analog design topics. Additionally, he provides direct customer support covering topics of operational and instrumentation amplifiers as well as other analog IC’s and responds to E2E forum questions across TI product lines regarding statistical guarantee of specifications and long-term shift of various IC's parameters.
