Abstract:
Systems and methods for reducing variability in the output impedance of an integrated switch-mode power amplifier (PA) split the output impedance between passive resistor, which may be on-chip, and a MOSFET switch of the amplifier. The PA may have a single-ended configuration or a differential configuration having two single-ended structures operating with opposite phases. In one implementation, the size of the MOSFET switch is larger than that of the MOSFET switch implemented in a conventional PA, but the size is still acceptable to operate the PA at a desired frequency. In addition, a calibration approach may be utilized to ensure that the MOSFET switch has a controlled and calibrated ON resistance, thereby providing stable output power levels of the PA and ensuring consistency and repeatability in NMR measurements.

Claim (Index 17):
A method of reducing variability of an output impedance of an integrated switch-mode power amplifier (PA), the method comprising:\n providing a PA driver having at least one MOS device; providing a pre-driver for facilitating activation and deactivation of the PA driver; and adjusting a number of stripes of the at least one MOS device so to provide a desired impedance.
