We present here a simple three P-type MOSFET-based grounded memristor emulator model. The model is designed to achieve zero static power dissipation and is done so by eliminating the external DC supply i.e., no DC bias. The proposed memristor emulator model has extremely low dynamic power dissipation as well which comes to around 175 nW i.e., ∼ 67% improvement compared to recent work. A mathematical analysis is carried out to present the relevance of this design. Simulations were done on Cadence Virtuoso 90 nm technology node and fingerprints of the proposed memristor emulator were obtained. The layout area occupied by the model is approx 1154.69 μ m2 and an external capacitor is connected to add tunability to the circuit. Furthermore, Monte Carlo and corner analysis validate the robust nature of the design. Besides, simulations have been experimentally verified using CD-4007 CMOS integrated circuit (IC) to make the design practically feasible. Furthermore, the design offers advantages such as extremely less overall power consumption and smaller chip area that could possibly pave the path for fabrication using standard CMOS technologies. At last, an application of the proposed model depicting in-memory computation through a memristor emulator crossbar array is presented in brief.

A fully integrated CMOS precision full-wave rectifier
(2016-01-01)
Kumngern, Montree
This paper presents a new fully integrated high frequency precision full-wave rectifier, which is highly suitable for CMOS technology implementation. The structure comprises a voltage-to-current converter, current rectifiers and a current-to-voltage converter. When an input voltage signal is supplied, it will be converted into two symmetrical current signals by using dual-output operational transconductance amplifier. These current signals will be rectified by using junction diodes that can realize by MOS transistors and convert into an output voltage by using MOS resistor. Hence, the structure can be design by all solid-state. Simulated rectifier results based on a 0.5 μm CMOS technology demonstrates high operating frequency and high precise rectification. Temperature sensitivity of the circuit has also been compensated. Simulation results are included to show workability of the proposed circuit.

Junnapiya, Somyot
This paper presents a new electronically tunable voltage-mode quadrature sinusoidal oscillator employing four single-ended operational transconductance amplifiers (OTAs) and two grounded capacitors. In general, the single-ended OTA configuration is simpler than the multiple-output OTA counterpart and the requirement of grounded capacitors is preferable for an integrated circuit fabrication process. Therefore, the proposed circuit provides a simple circuitry by using only single-ended OTA and highly suitable for integrated circuit (IC) implementation by using grounded capacitors. The condition of oscillation and the frequency of oscillation of the circuit can be set orthogonally. The circuit also offers an electronic control of the frequency of oscillation through adjusting the bias currents of OTAs. The theoretical results are verified by PSPICE simulators. From simulation results, it can be expressed that the proposed circuit agrees well with theory. © 2012 IEEE.

Voltage-controlled floating resistor using differential difference amplifier
(2011-10-18)
Kumngern, Montree
This paper presents a new configuration to realize the voltage-controlled floating resistor, which is suitable for integrated circuit implementation. The proposed resistor is composed of MOS transistor operating in the non-saturation region, differential difference amplifier (DDA) and MOS voltage divider. The MOS transistor operating in the non-saturation region is used to configure a floating linear resistor. The DDA and the MOS transistor voltage divider are used for canceling the nonlinear component term of MOS transistor in the non-saturation region to obtain a linear current/voltage relationship. The DDA is employed to provide a simple summer of the circuit. The resistor circuit also offers an ease for realizing the voltage divider circuit and the temperature effect that includes in term of threshold voltage can be compensated. The performances of the proposed circuit are simulated with PSPICE to confirm the presented theory. © 2011 IEEE.

This paper describes a new electronically tunable four inputs and single output voltage-mode universal biquadratic filter based on simple CMOS operational transconductance amplifiers (OTAs) and grounded capacitors. The proposed filter provides low-pass, high-pass, band-pass, band-stop and all-pass voltage responses at a high impedance input terminal, which enable easy cascadability. The circuit parameters ω<inf>o</inf> and Q can be orthogonally set the circuit component. The parameter ω<inf>o</inf> also offers an electronic control by adjusting the transconductance gain of the OTA. For realizing all the filter responses, no critical component matching condition is required and all the parameter sensitivities are low. PSPICE simulation results are performed to confirm the theoretical analysis. © 2010 IEEE.
