Let $C_0(alpha)$ denote the class of concave univalent functions defined in the open unit disk $mathbb{D}$. Each function $f in C_{0}(alpha)$ maps the unit disk $mathbb{D}$ onto the complement of an unbounded convex set. In this paper, we study the mapping properties of this class under integral operators.

A novel architecture and design approach which make it possible to boost the bandwidth slew-rate performance of operational transconductance amplifiers (OTAs) are proposed employed a low-power OTA with top-of-class small-signal large-signal figures merit (FOMs). The makes enhance gain, for given power consumption capacitive load, achieving more than an order magnitude better comparable conventi...

In the present paper, we prove that if L is a nilpotent Lie algebra whose proper subalge- bras are all nilpotent of class at most n, then the class of L is at most bnd=(d 1)c, where b c denotes the integral part and d is the minimal number of generators of L.

This paper presents a 3 order 1.5-bit Continuous-Time Fully Differential Ʃ∆ modulator with distributed feedback for a class D audio amplifier, using BJT differential pairs to implement the integrator stages. By relying on simple gain blocks instead of operational amplifiers to build the loop filter, a simpler overall circuit is obtained, where the non-ideal effects are embedded in the loop filt...
