A CMOS transconductor for multi-mode application is presented. The transconductor includes a voltage-to-current converter and a current multiplier. Voltage-to-current conversion employs linear region MOS transistors, and the conversion features high linearity over a wide input swing range. The current multiplier, which operates in the weak inversion region, provides a wide transconductance tuni...
Accurate analog models of power system components are required in order to realize an analog computation engine for power systems. Analog computation is an area of continued interest. Among the advantages over traditional digital methods are physically realizable solutions and faster computation times. This paper focuses on the design, simulation, and hardware verification of a static transmiss...
The paper deals with current conveyor based design criteria for low power Miller operational transconductance amplifier. Its transconductance has been controlled by using second generation current conveyor (CCII), replacing input bias current (Ibias). Current-mode based electronics devices becoming more popular than with voltage mode. The performance is obtained through PSPICE simulations which...
A 2.4-GHz single-stage CMOS low noise amplifier (LNA) structure with ultra low power consumption is proposed. A current reuse technique is used to decrease power dissipation with increasing amplifier transconductance for the LNA. Thus, the same amplifier transconductance for the LNA will be achieved at decreased power dissipation. Also, due to the use of an inverter-type amplifier which has a s...
This paper proposes a signal processing methodology of communication system and realized that circuits using operational transconductance amplifier (OTA).

A nonlinear parameterizable macromodel fo r CMOS Operational Transconductance Amplijiers (OTAs) is presented. The macromodel captures the DC, AC and large signal features of the transistor level original circuit, thus modeling accurately its time domain and nonlinear performance. The main contribution of this work is to account for the bias-dependent transconductance nonlinearities in the circu...
MOSFETs with heavily doped regions at one or both ends of the channel exhibit qualitative differences in electrical behavior compared to devices with laterally uniform channel doping. These differences include a distinct peakiness in the transconductance near threshold, asymmetries in capacitances, and a surprising decrease in the statistical variation of the peak gain factor as channel length ...
