A METHOD AND APPARATUS TO LINEARIZE TRANSCONDUCTORS BY PREDISTORTION |
摘要 |
<p>A transconductor for providing an output current that is linear in the input voltage (Vin) comprises a main output transconductor (Ms, Mc) and a model transconductor (Msr1, Msr2, Mcr1, Mcr2) that are controlled by the same signal (Vc, Vc'). The latter transconductor (Msr1, Msr2, Mcr1, Mcr2) is comprised in a predistortion circuit (A), which measures the output of the model transconductor and the overall voltage input (Vin) to provide a control signal (Vc, Vc') for the transconductors that compensates for their non-linearity.</p> |
