loop gain การใช้

• In practice, the loop gain is initially larger than unity.
• The actual difference is determined by the DC loop gain.
• Loop gain and stability calculations were added for analog circuits.
• With a loop gain greater than one, the oscillator will start.
• A loop gain greater than one has a down side.
• In a stable oscillator, the average loop gain will be one.
• FDA has infinite open-loop gain, infinite noise.
• With a typical high open loop gain operational amplifier, the output saturates.
• CD does not correctly apply the term loop gain.
• The amount of distortion is related to the extra loop gain used for startup.
• There is increasingly less NFB at high frequencies due to the reduced loop gain.
• The oscillator is designed to have a small-signal loop gain greater than one.
• Additionally, the DC loop gains are generally smaller by about three decimal orders of magnitude.
• The algorithm used a loop gain of 0.98 with increasingly attenuating first order lowpass filters.
• The major obstacle to achieving high loop gains is the need to maintain system closed loop stability.
• Open-loop gain is defined as the amplification from input to output without any feedback applied.
• Ideally, an oscillator's loop gain will be unity according to the Barkhausen stability criterion.
• OL appears commonly in feedback analysis and is called the "'loop gain " '.
• The loop gain is a product of the very high amplifier gain and the very low bridge ratio.
• If the loop gain is sufficient, howling or squealing at the maximum power of the amplifier is possible.
