Linearity Improvement Technique for the Common-Source Transconductance Stage
نویسندگان
چکیده
A linearity improvement technique for a common-source transconductance stage is proposed. The proposed technique requires an additional MIM capacitor located in parallel with the intrinsic gate-source capacitor of a transistor. The origin of the linearity improvement is explained and the proposed technique is applied to a down-conversion mixer. From the simulation, the down-conversion mixer that adopts the proposed technique shows 4.5dB higher input IP3 than the conventional mixer.

This paper is based on analysis of a common source - common gate low noise transconductance amplifier (CS-CG LNTA). Conventional noise analyses equations are modified by considering to the low output impedance of the sub-micron transistors and also, parasitic gate-source capacitance. The calculated equations are more accurate than calculated equations in other works. Also, analyses show that th...
متن کاملLow-distortion low-voltage operational transconductance amplifier
Introduction: Recent research shows a high demand for highly linear operational transconductance amplifiers (OTAs) with an aim to reduce total harmonic distortion (THD) [1–4]. However, most of these linearisation techniques may present important drawbacks such as reduced effective transconductance and significant power consumption. On the other hand, low power supply and power consumption solut...

متن کاملLinearity Enhancement of Operational Transconductance Amplifier Using Source Degeneration
The signal to noise ratio and resolution of an analog to digital converter is governed by the linearity constraints of the basic building block, which is the Operational Transconductance Amplifier (OTA). The OTA design is based on MOS transistors that are inherently non linear and lead to performance deterioration. To overcome the non-linearities imposed by the OTA a resistive source degenerati...
