Low Noise Dc Power Supplies

چکیده
− Some measuring systems are very sensitive on disturbances incoming from power supplies. If no accumulators are used for their power supply, which ensure a minimum signal noise and transmission jamming signal from power network, special power supplies have to be constructed for them. An example of a possible influence of a disturbance, which spreads along to the power supply on high pure sine-wave signal source, is presented in our contribution, whereas the requirements on the power supply are also specified. Furthermore, an analysis of the construction of these sources is effected and a sample of the source construction and records are introduced.

متن کاملLow Noise Front-End Amplifier Dedicated to Monitor Very Low Amplitude Signal from Implantable Sensors
This paper describes a low-noise, low-power and lowvoltage analog front-end amplifier integrated in implantable electronic devices and dedicated to very low amplitude signal acquisition. Low noise and low DC offset are obtained by means of Chopper Stabilization (CHS) technique. In addition, due to adding a rail to rail input stage, low power supply (1.8V) and wide common mode input range (0-1.8...
متن کاملA Low Noise and Reliable CMOS I/O Buffer for Mixed Low Voltage Applications
Abstract: In this paper the design of a high voltage tolerant and reliable CMOS I/O buffer is proposed without using thick-oxide devices. In this presented design for mixed low voltage interface applications, it uses a simpler structure and therefore the circuit has good gate-oxide reliability. In addition, it is free of dc leakage current. No additional pad for dual power supplies is required ...

Experimental results of an active filter based onchip hybrid voltage converter are described in this paper. The area of the voltage converter is significantly less than the area of a conventional passive filter based DC-DC voltage converter or a low-dropout (LDO) regulator. Hence, the proposed circuit is appropriate for point-of-load voltage regulation for the noise sensitive portions of an int...
متن کاملSwitched Mode Power Supplies for DC to DC Conversion
Introduction The widespread use of battery operated portable devices such as cell phones and laptops has created the need for DC to DC conversion power supplies such as switched mode power supplies. According to an Electric Power Research Institute (EPRI) study [1], the amount of electricity that flowed through switched mode power supplies in 2004 was “6% of the national electric bill”. The pro...
