Abstract

Micro Oscillator Inc. (MOI) proposes to develop a greatly improved timer base capable of maintaining high frequency accuracy at shock loads up to 100,000 G. The timer base will use a combination of two novel circuits. The first circuit is based on a patented CMOS I.C. clock oscillator developed by MOI that is already being used by the Military in high shock weapon applications. This oscillator maintains +/- .5% accuracy and appears capable of meeting the 100,000 G shock requirement as is. The second circuit is a patent pending technique for calibrating the above mentioned clock oscillator I.C., increasing accuracy to the +/- .002% level. The main goal of proposed Phase I effort will be to design and analyze the timer base system. Laboratory bench testing of breadboard units built using commercially available parts will be done to measure actual system performance. This is necessary since computer simulation below +/- 1% tolerance is not reliable. An accurate I.C. oscillator will place the USA oscillator industry in a leadership position against competing crystal oscillator hybrids, which are now mostly imported. The I.C. is much smaller in size, and also available in bare die. The military also benefits by now having weapon systems able to take full advantage of advanced digital control systems that rely on accurate timing.
