inputs are differential and a differential amplifier is needed to properly drive them. Two other advantages of differential signaling are reduced even-order harmonics and increased dynamic range. This report focuses on integrated, fully-differential amplifiers, their inherent advantages, and their proper use. The second thing we see is that the gain is little more than a ratio of collector to emitter resistances. This is where splitting the emitter resistor into two parts comes in. In the equation, \(r_E\) is the swamping resistor \(R_{SW}\). The larger the swamping resistor, the lower the gain. The maximum gain will be achieved when \(R_{SW} = 0\).This fully differential input requirement is near universal for ADCs that convert at a high sample rate (e.g., pipeline ADCs at >10Msps) as well as for ADCs that achieve very high resolution, high linearity and low noise (e.g., SAR ADCs at ≥18 Bit and ≥100dB SNR). Therefore, to use those components, you have no choice but to convert your ...The cutoff frequency or corner frequency in electronics is the frequency either above or below which the power output of a circuit, such as a line, amplifier, or electronic filter (e.g. a high pass filter) has fallen to a given proportion of the power in the passband.
