Circuit for providing variable waveform excitation

A method comprising:

• gating a first H bridge circuit to an on state to provide voltage from a first voltage source to an electronic component;
• while voltage is being provided from the first voltage source to the electronic component, pre-gating a second H bridge circuit to the on state and preventing, by one or more anti-series diodes of the second H bridge circuit, the voltage from the first voltage source from passing through the second H bridge circuit;
• gating the first H bridge circuit to an off state to stop providing voltage from the first voltage source to the electronic component;
• and
• in response to the first H bridge circuit gating to the off state, allowing voltage from a second voltage source associated with the second H bridge circuit to be provided to the electronic component,
• wherein the voltage from the first voltage source and the second voltage source is provided to the electronic component in a predefined waveform.

An H bridge circuit comprising:

• a plurality of MOSFET transistors configured to conductively couple to a voltage source;
• a plurality of forward-biased diodes, each forward-biased diode of the plurality of forward-biased diodes corresponding to one MOSFET transistor of the plurality of MOSFET transistors;
• and
• one or more anti-series diodes configured to prevent current from a second voltage source from passing through the H bridge circuit in providing voltage to an electronic component to be measured using a predefined waveform formed from voltage from the voltage source and the second voltage source.
