Latest Patents

One of Dave Brown's latest patents is a transformer data coupler with high common mode immunity. This invention includes a transformer with primary and secondary windings, a data transmitter coupled to the primary winding, and a data receiver coupled to the secondary winding. The data transmitter features a first driver and a second driver, which are responsive to a data signal and a delayed version of the data signal. This design allows the primary winding to be supplied with pulses that represent the difference between the data signal and its delayed version. Additionally, the data coupler includes an AC path to ground from the secondary winding, which conducts common mode signals to ground via the inter-winding capacitance of the transformer.

Another notable patent by Dave Brown is also a transformer data coupler with high common mode immunity. This version comprises two CMOS drivers that are supplied with a data signal and a delayed version of the data signal. These drivers drive the primary winding of a transformer with narrow pulses of opposite polarity corresponding to the edges of the data signal. The secondary winding is coupled via a low pass filter to a data receiver, with a ground path for AC from one end of the secondary winding. The drivers are scaled with a specific ratio to equalize voltage drops in the drivers due to unequal common mode currents.
