LTCC Packaged Ring Oscillator Based Sensor for Evaluation of Cell Proliferation
A complementary metal-oxide-semiconductor (CMOS) chip biosensor was developed for cell viability monitoring based on an array of capacitance sensors utilizing a ring oscillator.The chip was packaged in a low temperature co-fired ceramic (LTCC) Dishwasher Drain Hose module with a flip chip bonding technique.A microcontroller operates the chip, while
