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...

متن کاملDesign of Low Power Low Voltage Bulk Driven Operational Transconductance Amplifier (bd-ota)
Operational Transconductance Amplifier (OTA) is one of the most significant building-blocks in integrated continuous-time filters. Here we design Low Power Low Voltage Bulk Driven OTA with a new concept of high-linearity OTA with controllable Transconductance is proposed. The OTA is simulated in a standard TSMC 0.18 mm CMOS process with a 0.6 V supply voltage. 1. INTRODUCTON Low-voltage (LV) an...
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 کاملExtreme low-voltage floating-gate CMOS transconductance amplifier
In this paper we present an ultra low-voltage (ULV) floating-gate (FG) transconductance amplifier The amplifier is can operate at supply voltages down to 0.3V in a standard digital double poly CMOS process . The amplifier consists of three subcircuits, the single input analog FG inverter, the additive (double input) analog FG inverter with tunable gain and a FG digital inverter. Preliminary mea...
