In this paper, a low noise high gain CMOS amplifier for minute nerve signals is presented. By using a mixture of weakand strong inversion transistors, optimal noise suppression in the amplifier is achieved. A continuous-time offsetcompensation technique is utilized in order to minimize impact on the amplifier input nodes. The method for signal recovery from noisy nerve signals is presented. A p...

Abstract The increasing demand for high performance, battery-operated, system-on-chip (SoC) in communication and computing has shifted the focus from traditional constraints (such as area, performance, cost and reliability) to power consumption. With the increasing integration level, energy consumption has become an important issue. Consequently much effort has been put in achieving lower dissi...

Differential circuits are often described by their differential gain and common mode rejection ratio (CMRR). This approach, however, neglects the effect that the common mode signal has on the transient response and stability of the circuit. This work shows that the actual behavior of differential circuits in front of common mode voltages is completely described by the common-to-differential mod...

A realization of the CMOS digitally programmable current follower (DP-CF) suitable for low-voltage high-frequency application is presented. To achieve very low input resistance, it is realized using a modification of a low-input resistance stage as an input stage. To achieve the precise digital control of the current gain, the current division technique is used. The proposed DP-CF can operate w...

The efficiency and lifetime of light-emitting-diode (LED) lamps are approaching and exceeding that of fluorescent lamps. LED light sources are finding more applications than conventional light bulbs due to their compactness, lower heat dissipation, real-time color changing capability and most importantly, long life which is much longer life than that of conventional offline power converters. In...
