  ripple noise
The linear regulator reduces ripple noise induced by the charge pump and its AC rejection attenuates noise from the incoming supply.
      
Ripple/noise is ed over a 20MHz bandwidth and may require the installation of external I/O caps to achieve listed performance.
      
More specifically, it provides the functions of setpoint tracking, disturbance rejection and ripple/noise suppression.
      
In addition, Doppler shift and ripple noise pitch might have enhanced distance judgments.
      


A new design for PZT driver is presented. The driver with unsymmetric power supply possesses some advantages of good linearity, low ripple noise, powerful payload capability, high frequency responsibility and stable repeatability. The shortage of the traditional PZT driver is overcomed and the requirement for anti-vibration interferometer is satisfied.

The authors introduce the principle of the traditional single-phase boost rectifier with power factor correction (PFC),analyze the current impact and the ripple noise problems owing to the diode reverse recovery about PFC main circuit which is in practical applications. A novel boost power factor correction circuit with tapped inductance is proposed. Some practical problems in UC3854 controlled PFC circuit such as cusp distortion,output voltage raising and so on,are analyzed and some solutions are given respectively. At the same time,protecting circuit for pins of UC3854 and current amplifier clamping circuit to limit the output voltage swing are designed. Simulation and experimental results prove that the boost PFC rectifier with the optimizing design is reliable,its power factor can reach 0.99. It also can be compatible with the popular PFC control circuit.
