High Accurate Howland Current Source: Output Constraints Analysis
Howland circuits have been widely used as powerful source for exciting tissue over a wide frequency range. When a Howland source is designed, the components are chosen so that the designed source has the desired characteristics. However, the operational amplifier limitations and resistor tolerances cause undesired behaviors. This work proposes to take into account the influence of the random di...
متن کاملA Novel ±0.5V Ultra High Current Drive and Output Voltage Headroom Current Output Stage with Very High Output Impedance
A novel ultra-high compliance, low power, very accurate and high output impedance current output stage (COS) with extremely high output current drive capability is proposed in this paper. The principle of operation of this unique structure is discussed, its most important formulas are derived and its outstanding performance is verified by HSPICE simulation in TSMC 0.18µm CMOS, BSIM3, and Level4...
متن کاملDesigning A Very High Output Resistance Current Source
Abstract— A new technique is proposed in this paper in order to design a current source in bipolar technology with very high output resistance while minimising output capacitance. Such techniques are useful in Electrical Impedance Tomography applications. First of all, D.C. relationships are established. Then, an expression based on the analysis of a simplified equivalent circuit, is formulated...

a novel ultra-high compliance, low power, very accurate and high output impedance current output stage (cos) with extremely high output current drive capability is proposed in this paper. the principle of operation of this unique structure is discussed, its most important formulas are derived and its outstanding performance is verified by hspice simulation in tsmc 0.18µm cmos, bsim3, and level4...
متن کاملA novel ultra-high compliance, high output impedance low power very accurate high performance current mirror
In this paper a novel ultra-high compliance, low power, very accurate and high output impedance current mirror/source is proposed. Deliberately composed elements and a good combination (for a mutual auto control action) of negative and positive feedbacks in the proposed circuit made it unique in gathering ultra-high compliances, high output impedance and high accuracy ever demanded merits. The ...
