Abstract
Two transconductance amplifiers are presented in which the concept of an input dependent bias current has been introduced. As a result, these amplifiers combine a very low standby power dissipation with a high driving capability. The first amplifier, suited for SC filters, is fairly small (0.075 mm/SUP 2/) and has a slew rate which is more than an order of magnitude better than micropower amplifiers presented earlier. The second amplifier can be used as a micropower buffer. Nearly the whole supply current is used to charge the load capacitor so that this amplifier has a high efficiency.Keywords
