WebHalf-power point. The half-power point is the point at which the output power has dropped to half of its peak value; that is, at a level of approximately -3 dB. [1] [a] In filters, optical filters, and electronic amplifiers, [2] the half-power point is also known as half-power bandwidth and is a commonly used definition for the cutoff frequency.

Gain bandwidth equation

WebApr 11, 2024 · This is known as the gain bandwidth product (GBP). Hence, any increase in gain is a dividing factor in the bandwidth. In the case of CFOAs, the cutoff frequency is a function of “1/(2*pi*R2*Cc)”. This means that the cutoff frequency can be chosen with the selection of “R2”, and that for a CFOA, the gain and bandwidth are independent. Web(Note that in the equations above, g 0 and g p are dimensionless gain coefficients, not the gain per unit length.) An implicit underlying assumption is that there is always a thermal …
