Title
A Fast Fpw-Based Protein Concentration Measurement System
Abstract
A fast protein concentration measurement system with two-port FPW (flexural plate wave) biosensors using a frequency-shift readout technique is presented in this paper. The proposed frequency-shift readout method employs a peak detecting scheme to measure the amount of resonant frequency shift. The frequency sweep range of the linear frequency generator is limited in 2 MHz to 10 MHz according to the characteristics of the FPW biosensors. The proposed frequency-shift readout circuit is verified on silicon using a standard 0.18 mu m CMOS technology. The power consumption of the proposed protein concentration measurement system is 48 mW given a 0.1 MHz system clock. The protein concentration measurement is read out in less than 10 minutes.
