LTC3202 Drive White Light LED Circuit
LTC3202 is a charge pump produced by Linear Technology Company,which does not need gating oscillator. The graph is the circuit of a drive white light LED powered by lithiumion batteries using LTC3202 charge pump. In order to overcome noise problems,LTC3202 uses linear control technology to make sure that the charge and discharge capacity of the conversion capacitance just meet the load current needs, and in each clock cycle,it remains a constant, thus ensuring they would not produce audio components. The graph is the circuit of a drive white light LED powered by lithiumion batteries using LTC3202 charge pump. (View)

Weak Pulse Signal Amplifier Circuit
The signals of flexible and carotid artery is one of important information sources in pathological researches. The electrical signals,which are changed from pulse signals by high sensitivity pressure sensor signals is very weak, and it can be displayed, recorded or acquired by the computer only via amplification through 69-70dB . Op-amp A1, A2, A3 constitute the typical data amplifier,and A4 forms proportional amplifier. Op-amp F324,which is high gain and low power consumption is used here. (View)
