Design of Low Power Consumption Programmable Control Filter

LUO Jian,CHEN Jie,MA Ding-kun,BAI Xin(School of Marine Engineering,Northwestern Polytechnical University,Xi'an 710072,China)  
With the wildly application of portable devices and battery-powered system,the demand of signal conditioning systems for low power consumption is rapidly increased.The New digital signal conditioning system also requires changing the signal bandwidth and cut-off frequency easily.A new scheme of low power consumption programmable control filter is designed.By using time control switched-capacitor filter chip LTC1068 and LTC1069,band-pass filter is achieved.And the master controller MSP430F5438 sets the high and low cut-off frequency.Through the test circuit,the result shows that the design can be actually used.
