An auto-sensitivity control circuit for wired CDMA bus interface

We had proposed an auto-sensitivity control circuit for DS-CDMA receiver circuit. The wired bus interface requires different sensitivities for different number of transmitter/receiver pairs. These changes make errors in the receiving data. We proposed circuit that controls the effect of using different numbers of transmitter/receiver pairs. Simulation results verified that with the auto-sensitivity control circuit, receiver circuit in DS-CDMA wired bus interface works well for range of 8 to 40 pairs of transmitter/receiver.
