ICsense

  Your ASIC development  More cases

This ASIC was designed as part of a disposable apparatus for tumor cell detection. The goal is to detect and characterize tumor cells in blood in only a few hours. To achieve this, tumor cells are extracted from the blood and put through an active sieve (developed by imec). ICsense developed the ASIC that does electrical cell impedance spectroscopy on all sieve holes to count the cells and determine the cell real and imaginary impedances. The read-out consists of all signal processing of the current through the measured impedance for every frequency to a digital output (I-to-V conversion, programmable amplification, filtering and analog-to-digital conversion). 

Features

• Multiplexed impedance spectroscopy of cells
• Highly-accurate cell impedance acquisition
• 10bit, 32kHz BW, low-power band pass delta-sigma ADC
