Low-Voltage and Low-Power CMOS Voltage-to-Current Converter
A CMOS voltage-to-current converter in weak inversion is presented in this Letter. It can operate for low supply voltage and its power consumption is also low. As the input voltage varies from −0.15 V to 0.15 V, the measured maximum linearity error for the proposed voltageto-current converter, is about 3.35%. Its power consumption is only 26 μW under the supply voltage of 2 V. The proposed volt...
متن کاملLvdc Rules – towards Industrial-scale Application of Low-voltage Direct Current in Public Power Distribution
The modern low-voltage direct current (LVDC) distribution system merges ICT, power electronics and conventional grid technologies into single system. This paper gives an overview to the LVDC RULES research project and presents its first key results. The foundations of the project are laid by the lessons learned during earlier research projects. Impacts of providing ancillary services for the ne...
متن کاملMethods for extra-low voltage transcranial direct current stimulation: current and time dependent impedance decreases.
OBJECTIVE Though tDCS is well tolerated, it is desirable to further limit the voltage applied for additional safety factors and optimized device design. We investigated the minimum voltage required for tDCS using 1.5 and 2.5mA. METHODS Impedance data has been collected prior to, during and after 18 tDCS sessions, using 1.5mA and 2.5mA tDCS currents and three different test current magnitudes....
متن کاملDirect Voltage and Current Injection Edward
Methods of directly coupling sources to cables for-EMP testing are reviewed. Effects of cable impedance, cable shielding, and structure in the vicini,ty of the cable are examined. Several practical coupling mechanisms are discussed .
متن کاملAn Ultra High CMRR Low Voltage Low Power Fully Differential Current Operational Amplifier (COA)
this paper presents a novel fully differential (FD) ultra high common mode rejection ratio (CMRR) current operational amplifier (COA) with very low input impedance. Its FD structure that attenuates common mode signals over all stages grants ultra high CMRR and power supply rejection ratio (PSRR) that makes it suitable for mixed mode and accurate applications. Its performance is verified by HSPI...
