Journal ArticleDOI
The flipped voltage follower: a useful cell for low-voltage low-power circuit design
Ramon G. Carvajal,Jaime Ramirez-Angulo,Antonio J. Lopez-Martin,Antonio Torralba,Juan Antonio Gómez Galán,Alfonso Carlosena,Fernando Muñoz Chavero +6 more
TL;DR: A design example showing the application of the FVF to build systems based on translinear loops is described which shows the potential of this cell for the design of high-performance low-power/low-voltage analog and mixed-signal circuits.
Journal ArticleDOI
Low-Voltage Super class AB CMOS OTA cells with very high slew rate and power efficiency
TL;DR: In this paper, a simple technique to achieve lowvoltage power-efficient class AB operational transconductance amplifiers (OTAs) is presented, which is based on the combination of class AB differential input stages and local commonmode feedback (LCMFB) which provides additional dynamic current boosting, increased gain-bandwidth product (GBW), and near-optimal current efficiency.
Journal ArticleDOI
Very low-voltage analog signal processing based on quasi-floating gate transistors
TL;DR: In this paper, a design principle for very low-voltage analog signal processing in CMOS technologies is presented, based on the use of quasi-floating gate (QFG) MOS transistors.
Journal ArticleDOI
A free but efficient low-voltage class-AB two-stage operational amplifier
TL;DR: A simple and efficient low-voltage two-stage operational amplifier with Class-AB output stage with large effective output current boosting factor and close to a factor 2 bandwidth enhancement is introduced.
Journal ArticleDOI
Super Class-AB OTAs With Adaptive Biasing and Dynamic Output Current Scaling
Juan Antonio Gómez Galán,Antonio J. Lopez-Martin,Ramon G. Carvajal,Jaime Ramirez-Angulo,C. Rubia-Marcos +4 more
TL;DR: A new family of single-stage super Class-AB operational transconductance amplifiers suitable for low-voltage operation and low power consumption is presented and three novel topologies are proposed featuring simplicity and compactness.
