| Abstract: | The design of electrocardiogram amplifier(ECG) is mainly composed of a preamplifier and a band-pass filter,which is made up of four LMC6035 CMOS operational amplifiers,some resistances and some capacitances.It can achieve high gain,high sensitivity and low noise.It can make electrocardiogram clear and stable.In the designing process,it is simulated to analyse its characters,to test its functions by using Orcad/PSPICE9.0.The software can help us optimize the electrocircuit design and shorten the development period. |
