High-precision Differential-Input Buffered and External Transconductance Amplifier for Low-voltage Low-power Applications

Popis výsledku v původním jazyce

Recently, the demand for low-voltage low-power integrated circuits design has grown dramatically. For battery operated devices both the supply voltage and the power consumption have to be lowered in order to prolong battery life. This paper presents an attractive approach to designing a low-voltage low-power high-precision differential-input buffered and external transconductance amplifier, DBeTA, based on the bulk-driven technique. The proposed DBeTA possesses rail-to-rail voltage swing capability at a low supply voltage of +- 400 mV and merely consumes 62 uW. The proposed circuit is a universal active element that offers more freedom during the design of current-, voltage-, or mixed-mode applications. The proposed circuit is particularly interesting for biomedical applications requiring low-voltage low-power operation capability where the processing signal frequency is limited to a few kHz. An oscillator circuit employing a minimum number of active and passive components has been utilized in this paper as one of many possible applications. The circuit contains only a single active element DBeTA, two capacitors and one resistor, which is very attractive for integrated circuit implementation. PSpice simulation results using the 0.18 um CMOS technology from TSMC are included to prove the unique results.
