50_MHz_high_accuracy_analog_multiplier_with_single_ended_output

Figure 5-34 shows an analog multiplier with single-ended output. The error is within 2% over the range from dc to 50 MHz, with feedthrough below -50 dB. Figure 5-35 shows the performance when a 20-MHz sine input is multiplied by the trace A waveform, The output (trace B) is a clean instantaneous representation of the X/Y input products, with ±1 V at full scale. To trim, adjust the capacitor for minimum output square-wave peaking. LINEAR TECHNOLOGY, APPLICATION NOTE 47, P. 45.
