Opis:: This paper discusses a mem-capacitor circuit which is based on two MO-OTA along with a multiplier and 4 passive elements. This circuit is a charge-controlled memcapacitor emulator which is independent of any memristor also it consists the feature of electronic tunability. Additionally, this circuit is simpler and uses less hardware because it lacks a mutator and uses fewer active-passive components. The circuit behaviour is justified through various simulations in cadence Orcad tool with 180nm CMOS TSMC parameters. Additionally, conclusions from simulations and theory are validated experimentally through commercially available IC.

Voltage Differencing Voltage Transconductance Amplifier
Opis:: This paper presents a new realization of a first-order mixed-mode (Voltage input Current output) (MM) all-pass filter (APF) using the recently proposed modern active building block (ABB), namely the Voltage Differencing Voltage Transconductance Amplifier (VDVTA). The MM APF is made using minimum number of components, namely a single VDVTA and one grounded capacitor. The circuit does not use any external resistors and offers the advantages of current-tunable pole frequency, low input impedance and high output impedance. PSPICE simulation results are included to verify the workability of the circuit.

Opis:: A steady-state model of partially-depleted (PD) SOI MOSFETs I-V characteristics in subthreshold range is presented. Phenomena, which must be accounted for in current continuity equation, which is a key equation of the PD SOI MOSFETs model are summarized. A model of diffusion-based conduction in a weakly-inverted channel is described. This model takes into account channel length modulation, drift of carriers in the "pinch-off" region and avalanche multiplication triggered by these carriers. Characteristics of the presented model are shown and briefly discussed.

Tematy:: transconductance amplifier

OTA-C filter
Opis:: In this paper, the MOS differential pair driven simultaneously from gates and bulk terminals is described. An approximated analytical solution of the voltage to current transfer function has been found for the proposed circuit. Four possible combinations of gate and bulk connections of the input signal are presented. Basing on the configuration giving the best linearity, the operational transconductance amplifier (OTA) has been designed and compared, by computer simulations, to the amplifier utilizing the gate driven classic MOS pair. 3rd order filters using the OTAs with linearized and simple MOS pair have been designed and the resulting parameters have been compared. Linearization through the presented simultaneous use of gate and bulk terminals seems to be useful for low voltage applications.

Tematy:: current differencing transconductance amplifier

Opis:: This paper introduces a new current mode component called Modified Current Differencing Transconductance Amplifier (MCDTA). Important parameters of the circuit i.e. input resistance, z terminal resistance and transconductance of the output stage can be tuned electrically. The circuit can be implemented in linear and non-linear analog signal processing. The paper presents an example of the MCDTA application - a complete quadrature oscillator with the amplitude regulation. The functionality of the example circuit and its tuning capability were proved by the SPICE simulation results.
