Abstract :
A new voltage follower with ultra low output resistance and wide swing as features is proposed. A comparison of output resistance and signal swing among some voltage followers is made. The new voltage follower is developed in 0.18 um CMOS process and 1.5 V supply voltage. The THD of output voltage can still maintain around 0.1% when 1 MHz 0.8 V input voltage swing is applied. Simulation results show that the newly introduced voltage follower has optimal characteristics.
