New lossless inductance simulators realization using a minimum active and passive components

Voltage-controlled dual slope operation square/triangular wave generator and its application as a dual mode operation pulse width modulator employing differential voltage current conveyors

“…At this point, V o1 switches its output level to the positive saturation level V o þ , and the operation returns to on-duty cycle mode to begin a new cycle. The currents I X2 and I Z2 in this state are expressed in (12), and (13). Eqs.…”

“…Eqs. (9), (10), (12), and (13) show that by setting I X2 ¼I Z2 , V TH and V TL can be derived by (14).…”

“…In the past few years, development and design methods employing current-mode (CM) active building blocks have attracted a great deal of attention from analog circuit designers because they offer advantages over traditional operational amplifiers. These advantages include higher bandwidth, better accuracy, larger dynamic range, and simplicity of implementation [3][4][5][6][7][8][9][10][11][12][13]. Previous studies have presented voltage-mode (VM) realizations of square/triangular wave generators using a variety of active building blocks [1,[14][15][16][17][18][19][20].…”

New grounded immittance function simulators using single current feedback operational amplifier

“…Use of commercially unavailable integrated circuits such as the differential voltage current conveyor (DVCC); see for example [2,3], the fully differential second-generation current conveyor (FDCCII); see for example [5,23], the third-generation current conveyor (CCIII); see for example [7,8], the current differencing buffered amplifier (CDBA); see for example [9], the operational transresistance amplifier (OTRA); see for example [13], the gain-variable third-generation current conveyor (GVCCIII); see for example [16], the modified inverting first-generation current conveyor (MICCI); see for example [17], the modified currentfeedback operational amplifier (MCFOA); see for example [18], the current-controlled second-generation current conveyor (CCCII); see for example [20,22], the dual-x second-generation current conveyor (DXCCII); see for example [24] and the dual-output second-generation current conveyor (DO-CCII); see for example [25]. 2.…”

New active-only grounded inductance simulator employing current-mode approach suitable for wide band operation

“…There are several inductance simulator circuits published in the literature employing various active circuit building blocks such as current conveyors (CCIIs) (Pal 1981a,b;Higashimura and Fukui 1987;Kiranon and Pawarangkoon 1997;Ozoguz and Acar 1998), four terminal floating nullors (FTFNs) (Higashimura and Fukui 1993), voltage-mode operational amplifiers (VOA) (Ishida, Fukui and Ebisutani 1986;Khan, Ahmed and Minhaj 1992;Ohtsuki, Miyagawa, Ishida and Fukui 1999;Ohtsuki, Kawaoka, Miyagawa, Ishida and Fukui 2001), FDCCIIs (Kacar 2010), DO-CCIIs (Sagbas, Ayten, Sedef and Koksal 2009) and CCIIs with compensated parasitic resistance (Ferri, Guerrini and Diqual 2003;Yuce 2008). Inductance simulators built with CCIIs and FTFNs use passive components and thus require a large chip area during implementation.…”
