Bipolar class AB folded cascode operational amplifier for high-speed applications |
摘要 |
The present invention (800) comprises an operational amplifier with a first stage comparator circuit (801) for biasing a second stage folded cascode amplifier circuit (802). The result is that the input differential voltage signal to output current signal is transformed from a tanh function to a sinh function. The present invention provides the low noise, low distortion, high gain, wide bandwidth and good DC performance characteristics of the folded cascode op-amp configuration, with much improved slew rate.
