The trans-admittance-mode (TAM) might act as a transforming bridge for voltage-mode to current-mode conversion. In this study a new low voltage operated electronically tunable TAM biquad filter structure realizing all the seven standard filtering functions namely; low-pass (LP), band-pass (BP), high-pass (HP), regular-notch (RN), low-pass-notch (LPN), high-pass-notch (HPN) and all-pass (AP) fro...

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 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...

A CMOS voltage-to-current converter in weak inversion is presented in this Letter. It can operate for low supply voltage and its power consumption is also low. As the input voltage varies from −0.15 V to 0.15 V, the measured maximum linearity error for the proposed voltageto-current converter, is about 3.35%. Its power consumption is only 26 μW under the supply voltage of 2 V. The proposed volt...

A low-voltage and low-power voltage mode adder/subtractor using MOSFETs in weakinversion is presented in this paper. Since the MOSFETs in the proposed circuit are biased in weak inversion, consequently its power dissipation is very low. The proposed circuit has been simulated with the HSPICE using a N-well 0.35μm 2p4m process and the results show that, under the supply voltage of 1V, the power ...

of the Thesis Fully Integrated Hybrid Voltage Regulator for Low Voltage Applications by Yongwan Park Master of Science in Electrical Engineering Stony Brook University 2016 A novel hybrid regulator topology is proposed to alleviate the weaknesses of existing hybrid topologies. Contrary to the dominant existing practice, a switchedcapacitor converter and a resistorless LDO operate in a parallel ...
