Cet article propose une nouvelle méthode pour réaliser un étage d'entrée pour un amplificateur à transconductance opérationnel (OTA) rail à rail. L'étage d'entrée proposé est constitué de MOSFET de type monocanal. Par conséquent, aucune correspondance n'est nécessaire entre les MOSFET à canal N et les MOSFET à canal P contrairement aux méthodes conventionnelles. L'étage d'entrée proposé est composé de trois MOSFET qui fonctionnent dans plusieurs régions de fonctionnement. Néanmoins, une combinaison des courants de drain des trois MOSFET est proportionnelle à une tension d'entrée qui varie entre deux rails d'alimentation. Une configuration de circuit pour réaliser un OTA rail à rail avec l'étage d'entrée proposé est également proposée. Le principe de fonctionnement et la validité du circuit proposé sont confirmés par des simulations HSPICE.

Abstract: This paper proposes a novel method to realize an input stage for a rail-to-rail operational transconductance amplifier (OTA). The proposed input stage consists of single channel type MOSFETs. Therefore no matching is necessary between n-channel MOSFETs and p-channel MOSFETs unlike conventional methods. The proposed input stage is composed of three MOSFETs which operate in plural operation regions. Nevertheless a combination of drain currents of the three MOSFETs is proportional to an input voltage which varies between two power-supply rails. A circuit configuration to realize a rail-to-rail OTA with the proposed input stage is also proposed. The operation principle and the validity of the proposed circuit are confirmed through HSPICE simulations.
