Ultra low-voltage CMOS transconductance amplifiers

Simple and symmetrical ultra low-voltage current mode analog circuits and autozeroing amplifiers are presented. The low-voltage analog circuits are based on low-voltage inverters resembling precharge digital logic. Ultra low-voltage analog circuits can be operated at supply voltages down to 250 mV with rail-to-rail input and output swing. The output current of the ultra low-voltage symmetrical ...

Low-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...

Ultra low-voltage floating-gate transconductance amplifier

The minimum supply voltage in low-voltage circuits can be defined as Vsup,min = 2(Vgs+Vsat) [1]. Low-voltage circuits are able to operate on a supply voltage of two stacked gate-source voltages and two saturation voltages. Differential amplifiers are biased with a transistor feeding a differential pair, where the current level is set by the bias transistor. The minimum input voltage in a NMOS i...

A Novel Low Voltage, Low Power and High Gain Operational Amplifier Using Negative Resistance and Self Cascode Transistors

In this work a low power, low voltage and high gain operational amplifier is proposed. For this purpose a negative resistance structure is used in parallel with output to improve the achievable gain. Because of using self cascode transistors in the output, the proposed structure remains approximately constant in a relatively large output voltage swing causing an invariable gain. To evaluate the...
