Latest Patents

Motoroiu's latest patents include innovative designs that enhance the performance of chopper amplifiers and instrumentation amplifiers. One of his patents, titled "Power-on-reset and phase comparator for chopper amplifiers," describes an apparatus that includes an amplifier, an input port, a first modulator circuit, and a correction circuit. This correction circuit is designed to determine a common mode voltage of the input port and manipulate a clock signal to generate a second clock signal for the modulator circuit. Additionally, it can reset the second clock signal if it is out of phase with a third clock signal.

Another significant patent is "Dynamic correction of gain error in current-feedback instrumentation amplifiers." This invention features a current feedback instrumentation amplifier (CFIA) that utilizes a differential pair with degeneration to amplify small differential voltages amidst large common-mode voltages. The CFIA includes input and feedback transconductors, along with a chopping modulator circuit that periodically swaps tail current sources. This innovative approach effectively cancels out the gain error caused by mismatched tail currents.
