摘要： Bias current generation circuits and systems are disclosed. In one embodiment, a gain boosting cascode system comprises a cascode based on a transconductance amplifier and a current buffer and a gain booster circuit coupled to the cascode optimally boosting a gain of the cascode by maintaining the transconductance amplifier and the current buffer in their respective saturation regions. The gain booster circuit is based on one or more feedback amplifiers coupled in series with a main voltage control transistor. The main voltage control transistor is maintained in a triode region, and the voltage at the drain of the main voltage control transistor can be set by passing an appropriate amount of current through the main voltage control transistor. This in turn would keep the transconductance amplifier and the current buffer in their respective saturation regions, thus generating the optimal gain for the gain boosted cascode system.

摘要： A current mirror circuit suitable for use as an amplifier active load having first and second MOS transistors connected in series together with third and fourth MOS transistors connected in series. The first and third transistors have common source and common gate connections, with the drain of the second transistor forming the current mirror input and the drain of the fourth transistor forming the current mirror output. Bias circuitry operates to maintain the second transistor in the triode region of operation and to maintain the fourth transistor in the saturation region of operation. The second transistor has a small geometry compared to the fourth transistor so as to enhance the transient response performance of the current mirror circuit.
