“…Here the analysis and design have been carried out by using an integrated technology process, the CMOS 150 nm technology process from LFoundry, showing at the same time the feasibility of the proposed solution to be realized at integrated level, that is the main goal for practical applications. The solution here adopted is based on the use of a secondgeneration current conveyor (VCII) [34][35], obtained for duality from the second-generation current conveyor (CCII) [36][37]. The VCII realizes internally a current buffer followed by a voltage buffer ( Fig.…”

“…So, the gain is independent from input and output external loads. In addition, it is important to notice that the VCII has the further characteristic of having the gain value independent from the useful bandwidth [34] and also this peculiarity makes it particularly suitable for the considered application.…”

“…First of all, it is a mixed voltage-mode current-mode design, and thanks to this choice, it is able to merge the two different design conceptions, taking advantage of both of them. In addition, it is the first discrete hybrid interface designed at the transistor level, making use of the so-called second-generation voltage conveyor (VCII) [17][18][19][20]. To the best of our knowledge, no other discrete VCIIs have been presented in the literature up to now.…”

This work presents the design of a discrete second-generation voltage conveyor (VCII) and its capability to be used as electronic interface for silicon photomultipliers. The design addressed here exploits directly at the transistor level, with commercial components, the proposed interface; the obtained performance is valuable considering both the discrete elements and the application. The architecture adopted here realizes a transimpedance amplifier that is also able to drive very high input impedance, as usually requested by photons detection. Schematic and circuital design of the discrete second-generation voltage conveyor is presented and discussed. The complete circuit interface requires a bias current of 20 mA with a dual 5V supply voltage; it has a useful bandwidth of about 106 MHz, and considering also the reduced dimensions, it is a good candidate to be used in portable applications without the need of high-cost dedicated integrated circuits.

“…This feature makes VCIIs a highly suitable candidate to replace CCIIs in applications requiring voltage output because they alleviate the need for an extra voltage buffer. Recently, VCIIs have attracted the attention of researchers, and their applications in implementing filters, gyrators, oscillators, inverting and non-inverting voltage amplifiers, current to voltage converters, differentiators and integrators, and readout circuits have been reported [13][14][15][16][17][18][19][20].…”

“…The low voltage low power restrictions imposed by advanced technologies necessitate the design of a high performance VCII circuit that is able to operate under low supply voltages and to provide an appropriate voltage swing at the voltage output port. Since previous implementations of VCIIs have suffered from limited voltage swing at the voltage output port [14][15][16], in this paper, we propose a new low voltage low power VCII with improved voltage range (rail-to-rail, (RtR)) characteristic at the output of terminal Z, but also at the input of terminal X. This will fully take advantage of its inherent transimpedance amplifier (TIA) behavior, making it suitable in applications where information has to be converted from the current to the voltage domain [21,22].…”

In this paper, a novel low voltage low power CMOS second generation voltage conveyor (VCII) with an improved voltage range at both the X and Z terminals is presented. The proposed VCII is formed by a current buffer based on a class AB regulated common-gate stage and a modified rail-to-rail voltage buffer. Spice simulation results using LFoundry 0.15 μm low-Vth CMOS technology with a ±0.9 V supply voltage are provided to demonstrate the validity of the designed circuit. Thanks to the class AB behavior, from a bias current of 10 µA, the proposed VCII is capable of driving 0.5 mA on the X terminal, with a total power consumption of 120 µW. The allowed voltage swing on the Z terminal is at least equal to ±0.83 V, while on the X terminals it is ±0.72 V. Both DC and AC voltage and current gains are provided, and time domain simulations, where the voltage conveyor is used as a transimpedance amplifier (TIA), are also presented. A final table that summarizes the main features of the circuit, comparing them with the literature, is also given.
