A new family of very low-voltage analog circuits based on quasi-floating-gate transistors

Design of Two-Stage Class AB CMOS Buffers: A Systematic Approach

“…Note, however, that the product GB=A ol f p1 is the same as the class A follower. For C L >C X , the increase in C X from (9) is not significant in (8) and the increase in the numerator of f p2 shifts f p2 to higher frequencies. From (4), this may slightly increase bandwidth of the class AB buffer versus its class A counterpart, as shown in Table 1.…”

“…The technique is based on the use of quasifloating gate (QFG) techniques [8]- [11] which allow the inclusion of a class AB operation without requiring additional power consumption or supply voltage and featuring a simple and accurate control of quiescent currents.…”

Achieving Energy Efficiency in Analogue and Mixed Signal Integrated Circuit Design

“…In this work, the device coined as ''quasi'' floating gate MOS (Ramírez-Angulo et al, 2003) is used to replace the passive resistors. A QFG MOS transistor consists of a MOS transistor with capacitive gate voltage averaging biased using a large resistive element R large , as shown in Fig.…”

A reaction‐diffusion model performing stripe‐ and spot‐image restoration and its LSI implementation

“…Since these charges affect the offset of the amplifier, they must be discharged. To this end, a quasifloating-gate (QFG) is used in the FG section [6]. Specifically, a high resistance is added between the FG and the ground so that the gate of the transistor is pseudo-floating.…”
