Multi-stage amplifier with frequency compensation
A multi-stage amplifier (21) has three or more amplifier stages (A1, A2 and A3) arranged in a capacitatively nested configuration for frequency compensation. The technique consists of nesting two of the stages (A1, A2) together with a pole-splitting capacitor (C1) to form a stable device (11) and th...

| Zusammenfassung: | A multi-stage amplifier (21) has three or more amplifier stages (A1, A2 and A3) arranged in a capacitatively nested configuration for frequency compensation. The technique consists of nesting two of the stages (A1, A2) together with a pole-splitting capacitor (C1) to form a stable device (11) and then nesting this device and a third (A3) of the stages together with another pole-splitting capacitor (C2) to form the amplifier (21). |
