Article: Low-voltage high-performance voltage-mode and current-mode WTA circuits based on flipped voltage followers
[show abstract] [hide abstract]
ABSTRACT: A new low-voltage CMOS winner-take-all (WTA) circuit is presented. The proposed circuit exhibits a linear increase of complexity with the number of inputs at the rate of only three transistors per input and it is based on a modified version of the common source scheme. In this case, each input follower is enhanced by local shunt feedback to increase its gain and to reduce its output impedance. Simulations demonstrate the potential of the circuit to operate at very high speed, with high precision and with a supply voltage close to a transistor's threshold voltage. Experimental verification of the circuit using a 0.5-μm CMOS technology is also provided.Circuits and Systems II: Express Briefs, IEEE Transactions on 08/2005; · 1.41 Impact Factor -
Conference Proceeding: Low-voltage low-power super class-AB CMOS op-amp with rail-to-rail input/output swing
[show abstract] [hide abstract]
ABSTRACT: A low-voltage CMOS class AB OTA with rail to rail input/output swing, low supply voltage and very high slew rate is presented. The scheme is based on a combination of floating gate transistors, local common-mode feedback and class AB input. The proposed OTA does not suffer from typical reliability problems related with initial charge trapped in the floating gates devices. Simulation and experimental in 0.5 μm CMOS technology verify the scheme operating with 1V dual supply and 1.9 Vp-p input and output swing.Devices, Circuits and Systems, 2004.
