Summary: 
High integration and low power operation of integrated circuits make noise sensitivity high. Therefore, it is important to reduce noise of circuits. A bias-offset transconductor is known as a linear transconductor. It is expected that noise sensitivity of the transconductor becomes higher due to improvement of linearity and reduction of power dissipation. This paper proposes a design method to reduce noise considering high linearity, reduction of power dissipation and small circuit size.
