Ultra-Low voltage Tunable transconductor Based on Bulk-Driven quasi-Floating-gate Technique

This paper presents ultra-low voltage transconductor using a new bulk-driven quasi-°oatinggate technique (BD-QFG). This technique leads to signi ̄cant increase in the transconductance and the bandwidth values of the MOS transistor (MOST) under ultra-low voltage condition. The proposed CMOS structure of the transconductor is capable to work with ultra-low supply voltage of 300mV and low power con...

Design of Low Voltage CMOS OTA Using Bulk-Driven Technique

Background/Objectives: The main objective was to design a CMOS Operational Transconductance Amplifier (OTA) for biomedical applications and high speed transmission with an operating voltage 0.4 V. Methods/Statistical Analysis: In this paper we have proposed an OTA using bulk driven technique. The transistors are working in weak-inversion. The design was simulated using conventional transistors....

Designing a Full Adder Circuit Based on Quasi-Floating Gate

Since in designing the full adder circuits, full adders have been generally taken into account, so as in this paper it has been attempted to represent a full adder cell with a significant efficiency of power, speed and leakage current levels. For this objective, a comparison between five full adder circuits has been provided. Applying floating gate technology and refresh circuits in the full ad...

Quasi-Floating Gate MOSFET based Current-to-Voltage Converter

This paper demonstrates the use of quasi-floating gate MOSFET (QFGMOS) in the design of a current-to-voltage converter that operates for the input current range of 0 to 50?A. The workability of the circuit has been verified using SPICE simulations for 0. 18?m CMOS technology with the supply voltages of ±0. 5V. From the simulation results, it has been observed that the proposed circuit has low p...

An Autozeroing Floating-gate Bandpass Filter

We have developed a bandpass oating-gate ampli er that uses tunneling and pFET hot-electron injection to set its DC operating point adaptively. Because the gate currents are small, the circuit exhibits a high-pass characteristic with a cuto frequency less than 1 Hz. The high-frequency cuto is controlled electronically, as is done in continuous-time lters. We have derived analytical models that ...
