A low-voltage current-mode integrator is presented for a continuous-time baseband channel selection filter of wireless communication systems. Fully-balanced current-mirror structure with additional cascode transistors operated in linear region enables low-voltage and low-power dissipation properties as well as voltage-controllable cutoff frequencies over a broad frequency range. A channel selec...

A high performance FGMOS based current mirrors at low supply voltage is proposed in this paper. A combination of floating gate and CMOS technology is used to design this new simple current mirror at low supply voltage of 0.5V using 180nm CMOS technology. Very low input impedance of 14Ω with increased input voltage swing. In addition to accurate current copy, a very high output impedance of 5GΩ ...

Current or voltage-type sense amplifier (SA) is the key element for sensing process of RFID transponder EEPROM. The performance of the EEPROM is influenced by the SA features like memory access time, power dissipation and the reliability. However, larger current or power dissipation put limitations on using current type SA with respect to voltage type SA. A low voltage SA with lower current con...

In a photovoltaic system, sun light energy is converted to electricity. The generatedelectricity has a low DC voltage. In order to increase voltage generated by photovoltaic cells (PV),an additive DC-DC converter is required to raise the low voltage to a good level which provides theconditions for connection to DC-DC converters. Low wastes, low costs, and high efficiency are someother specifica...

The electric power grid is a critical infrastructure that delivers electric power from electricity sources to consumers. Currently, renewable and distributed sources of electricity, as well as new technologies that introduce large loads, are significantly changing the load profiles at the low-voltage grid. This trend calls for reassessing the structure of the low-voltage grid to see if it can s...

The minimum supply voltage in low-voltage circuits can be defined as Vsup,min = 2(Vgs+Vsat) [1]. Low-voltage circuits are able to operate on a supply voltage of two stacked gate-source voltages and two saturation voltages. Differential amplifiers are biased with a transistor feeding a differential pair, where the current level is set by the bias transistor. The minimum input voltage in a NMOS i...

The main advantages of Multilevel Inverters mentioned are low-key volta...

There is rapid expansion in the use of short range digital wireless systems [1], using the license-free allocations around 915 MHz in the USA and 869 MHz in Europe that permit up to 1 watt output power. These RF systems now use digital signal processing (DSP) for modulation and demodulation so to get better circuit packing density, and take advantage of finer IC process geometries that generall...
