Conventional switch-mode dc-dc converters are operated at frequencies in the order of hundreds of kHz to single MHz. Switching frequencies in the order of tens of MHz would enable applications of RF converters in low power communications and computing integrated circuits with dynamic voltage scaling. Controllers for these converters would have to operate with a bandwidth in the GHz range. The m...

Voltage/current-mode universal biquadratic filter using single plus-type second-generation current conveyor (CCII), two capacitors and two resistors has been presented. The proposed voltage-mode circuit has three inputs and two outputs and can realize all the standard filter functions, which are, lowpass, bandpass, highpass, notch and allpass filters, without changing the circuit topology. One ...

A new current-mode band-pass filter using the inverting second-generation current conveyor (ICCII) is introduced. The circuit is generated from a frequency-dependent negative resistance (FDNR)-C circuit realized using ICCII+. It is observed that a voltagemode band-pass filter using two CCII+ has similar transfer function to this current-mode filter. The adjoint network theorem is used to demons...

The advent of differential voltage current conveyor(DVCC) has opened up new avenues in analog circuit design. In the present work, a DVCC has been employed to designcurrent-mode first-order continuous-time analog filters. Parameter tunability is achieved by the use of a two-MOSFET electronicresistor which exhibits variation in resistance in accordancewith a control voltage. The proposed circuit...

In this paper, design of a CMOS tunable versatile filter using current conveyor (CC) is presented. The filter is realized at the same time as on the chip is tunable for low pass, band pass, high pass, and elliptical notch filter. The circuit is utilizes two current conveyors, one Operational Trans-conductance Amplifier (OTA), four resistors and two grounded capacitors, ideal for integration. It...

A current-mode universal biquadratic filter is presented. The architecture has three input terminals, one output terminal using one differential difference current conveyor (DDCC), two grounded capacitors and two resistors.

The field of low-voltage low-power CMOS technology has grown rapidly in recent years; it is an essential prerequisite particularly for portable electronic equipment and implantable medical devices due to its influence on battery lifetime. Recently, significant improvements in implementing circuits working in the low-voltage lowpower area have been achieved, but circuit designers face severe cha...

In this work, an electronically tunable universal voltage-mode biquadratic filter with single input and five outputs is introduced. The proposed filter structure only employs three differential difference current conveyor transconductance amplifiers (DDCCTAs) and two grounded capacitors without needing any external passive resistor. All the five standard biquadratic filter functions; lowpass, b...
