2. The high-speed summing amplifier can sum as many as four input voltages without the need for an inverter to change the sign of the output. Figure 3 is the performance photo at 1 MHz.

Many applications require a sampling circuit whose output is inverted with regard to the respective sample of an input signal. A simple approach is a cascade of a common noninverting sample-and-hold ...

In some applications, a linear amplifier is required which has different gains with regard to the polarity of the input signal. Figure 1 shows an inverting amplifier which is linear within the second ...
