In turn, many of Hall's former employees such as David Fullagar went on to become major Silicon Valley contributors. "John's professional contributions over a 60-year career were matched only by his generosity toward the people around him," said Cindy L Johnson,. "He is greatly missed by his family and friends." In accordance with Hall's wishes Linear Integrated Systems will continue its work as a world-class developer and producer of specialized discrete semiconductors, A year before Mr. Hall died he appointed Cindy L. Johnson as president. In 2014 the board of directors appointed Cindy L. Johnson as CEO. Chief Executive Officer Cindy L. Johnson Cindy L. Johnson has 37 years of Silicon Valley experience, starting her career with MicroPower Systems in 1977. Johnson began her career working for John H. Hall at Micro Power Systems and in 1986 was a co-founder of Linear Integrated Systems, Inc. Johnson has served as president and chief financial officer (CFO) of Linear and will continue as CFO in addition to assuming the position of CEO.
