By changing the structure of its input-circuit,it can be used as a current-mode filter or a voltage-mode filter,and each of the both can simultaneously implement the fourth-order highpass,bandpassand lowpass flter functions.

In this paper a new amorphous silicon thin-film transistor (a-Si TFT) pixel circuit for an active matrix organic light-emitting diode (AMOLED) employing a voltage programming has been proposed which consists of five switching TFTs, one driving TFT, and one capacitor.
The electrical resistance was also measured in an ac pulsed low-voltage mode.
The dependence of the limiting discharge current of cations on their concentrationc1 in a high-voltage mode is simulated numerically on a computer.
Relationship between the Inversion Current of Metal Dissolution and Parameters of Its Deposition at High-Voltage Mode in Support
The model predicts the existence of two discharge operating modes with thermionic electron emission on the cathode: a low-voltage mode with a high current density and a high-voltage mode with a significantly lower current density.
Both common methods of DC/DC converter control, Voltage Mode Control and Current Mode Control, are considered.
The dual relationshp between current-mode circuits and voltage-modecircuits is discussed,according to the node voltage KCL equations and the eloop currentKVL equations Dual transformation method is presented to derive current-mode cir-cuit. Examples are given to sbw that this method is useful to design current-mode circults.
Three approacbes of filter are deliberated namely:CC(current converyer)filter de-rived from OA(operation amplifer)filter , that from state variable circuit and that from signal flow graph. They are derived from active RC filters and constructed with current conveyor instead formed the current-mode continuous-time filters.The circuits have the same passive sensitivity as that of the original one. If autocor-rection is applied,all the three being offered are suitably performed by integrated Circuit.
This paper aims to realize current-mode transfer functions by realizingadmittance driving point function Y_(11).R C passive ladder-structure current-mode filterscan be designed by properly selecting the poles and zeros of Y_(11).These current-mode circuits are similiar to the voltage-mode circuits.
