Slew rate enhancement based on use of squaring circuits
TL;DR: In this article, a squaring circuit is introduced that boosts the tail current source of an opamp to improve its slew rate, which operates as a differential voltage magnitude detector, which generates opamp tail currents proportional to the magnitude (square) of the opamp's differential input voltage.

A CMOS linear tunable transconductor for continuous-time tunable Gm-C filters
T. Sanchez-Rodriguez,C. Lujan-Martinez,Ramon G. Carvajal,Jaime Ramirez-Angulo,Antonio J. Lopez-Martin +4 more
TL;DR: In order to show the feasibility for the implementation of tunable Gm-C filters using the proposed transconductor, a 1 MHz tunable third order Chebyshev low-pass filter suitable for Bluetooth applications has been experimentally validated.
Journal ArticleDOI
A 1.2-V Current-Mode RMS-to-DC Converter Based on a Novel Two-Quadrant Electronically Simulated MOS Translinear Loop
Maite Martincorena-Arraiza,Carlos A. De La Cruz Blas,Jose Maria Algueta-Miguel,Antonio J. Lopez-Martin +3 more
TL;DR: A novel current-mode CMOS RMS-to-DC converter using translinear techniques is introduced, based on a squarer/divider cell that is implemented using an electronically simulated loop with a novel biasing scheme that allows its operation in two quadrants.
Proceedings ArticleDOI
Techniques for the Design of Low Voltage Power Efficient Analog and Mixed Signal Circuits
TL;DR: The use of new circuit design techniques are illustrated to achieve low-voltage class AB amplifiers that combine that combine to reduce power consumption and increase the lifetime of the battery.
Proceedings ArticleDOI
Wide gm adjustment range highly linear OTA with programmable mirrors operating in triode mode
TL;DR: In this paper, a very compact and highly linear CMOS OTA with very wide gain tuning range is presented, which uses a fixed gain linear V-I converter input stage and electronically programmable current mirrors working in triode.
