Abstract
An acquisition circuit for a vehicle or other system is provided. The system, for example, may include, but is not limited to a control moment gyroscope, and a fully differential ground isolated acquisition circuit communicatively connected to the control moment gyroscope and configured to acquire a differential data signal on the control moment gyroscope and output the differential data signal to at least one output node. The acquisition circuit may include, but is not limited to a ground reference correction circuit configured to recenter the differential data signal on at least one output node, and at least one ultra-high impedance output circuit coupled between the ground reference correction circuit and the input differential circuit.
