New high frequency memristorless and resistorless meminductor emulators using OTA and CDBA

Single Active Block-Based Emulators for Electronically Controllable Floating Meminductors and Memcapacitors

“…Equation ( 18) still represents a meminductor, with the additional effect of a total capacitance C p +C x-connected in parallel with the input port. The second term in (18) accounts for the impact of this parasitic capacitance. This effect can manifest as a shift in the pinched-hysteresis loop on the flux-current characteristics, deviating the pinch-off point from the origin.…”

“…Orman et al [17] devised an MIE employing a differential difference current conveyor (DDCC) with both hard and smooth switching behaviors. Yadav et al proposed an MIE utilizing two OTAs and one current differencing buffered amplifier (CDBA), operating up to 2 MHz; however, this implementation necessitated 37 CMOS transistors and six current sources, which was considered excessive [18]. Bhardwaj and Srivastava devised an MIE employing a modified VDCC (MVDCC) and OTA, requiring a total of 38 transistors and operating up to 300 kHz.…”

High -Frequency Tunable Grounded and Floating Incremental-Decremental Meminductor Emula-tors and its application as AM Modulator

“…Several circuits for emulating memristor-less meminductors are proposed in [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23], while meminductors formed using mutators are proposed in [24][25][26][27][28]. In [8], a memristor-less current and voltage-controlled meminductor emulator are reported using a second-generation current conveyor (CCII), adder, multiplier, and several passive components in the count.…”

“…The design reported in [17] is based on two OTAs and one differential voltage current conveyor (DVCC), and the design in [18] is based on one OTA and one VDTA. The topology in [19] reports a meminductor employing two OTAs and one current differencing buffered amplifier (CDBA), whereas [20] is based on two OTAs and one current differencing transconductance amplifier (CDTA). Meminductor design in [21] employs two CCIIs and one OTA, whereas design [22] is based on two VDTAs.…”

“…Moreover, [23] reports a design based on one modified voltage differencing current conveyor (MVDCC) and one OTA. However, all the designs reported in [8-12, 15-18, 20-23] realize only one type of meminductance emulator, i.e., the grounded or floating meminductor; only [19] realizes both grounded and floating meminductance emulator. Furthermore, the designs reported in [21][22][23] realize only one type of meminductance emulator and possess a low frequency of operation.…”
