TL;DR: In this article, a simple low voltage operational amplifier with an efficient class-AB output stage is introduced, where two biasing transistors are present in between common source stage and output stage.
Abstract: A simple low voltage operational amplifier is introduced with an efficient class-AB output stage. Two biasing transistors are present in between common source stage. This amplifier is simulated in 0.18 µm CMOS technology. The proposed class-AB amplifier is designed to operate from ±500 mV supplies. The simulated phase margin of proposed class-AB amplifier is 87° at the load of 10 kΩ∥1 pF. The class-AB amplifier's total compensation capacitance is 5 pF, which is less than 50% of conventional amplifiers. The unity gain frequency of proposed class-AB amplifier is 21.17 MHz, when driving a resistive load from 10 kΩ to 500 kΩ and capacitive loads from 1 pF to 5 pF. The slew rates of modified amplifier are 7.5 V/µs and 8.57 V/µs. This modified amplifier greatly increases the slew rate compared to the conventional circuits.

TL;DR: Eco-friendly synthesis of pimavanserin was developed from the key starting material 4-isobutoxy benzylamine in three different routes using water as solvent with advantage of easy workup, good yields of products and uses water as the solvent.
Abstract: Eco-friendly synthesis of pimavanserin was developed from the key starting material 4-isobutoxy benzylamine in three different routes using water as solvent. These reactions provide an advantage of easy workup, good yields of products and uses water as the solvent. No column purification was required for the isolation of the product.

TL;DR: In this paper, the authors prove coupled fixed point theorems of a self mapping satisfying a certain rational type contraction along with strict mixed monotone property in an ordered metric space.
Abstract: The aim of this paper is to prove some coupled fixed point theorems of a self mapping satisfying a certain rational type contraction along with strict mixed monotone property in an ordered metric space. Further, a result is presented for the uniqueness of a coupled fixed point under an order relation in a space. These results generalize and extend known existing results in the literature.
