2.3.3 PSpice-TI Simulation

Download the PSpice-TI simulation models for the relevant components from https://www.ti.com. Figure 2-14 shows the PSpice -TI simulation for the entire circuit.

Figure 2-15 Noise Contribution of the Proposal 3 Circuit

Figure 2-15 shows the noise contribution of the circuit. The output noise of 0.968 nV/√Hz at 1 kHz indicates that such a drive circuit can drive less than 192 channels simultaneously.
