Abstract
Systems, devices, and methods are provided for pulsed strain gauge topologies. A weight sensor assembly may comprise one or more load cells for receiving excitation pulses during a first state period of a duty cycle, sample and hold (S/H) circuitry connected to the one or more load cells that holds analog measurement signals from the one or more load cells, first filtering circuitry connected to the S/H circuitry for processing the analog measurement signals and producing a DC level signal, an amplification system connected to the filtering circuitry, for amplifying the DC level signal, second filtering circuitry connected to the amplification system for filtering power line noise, and analog-to-digital (ADC) circuitry connected to the second filtering circuitry. Examples of load cells described herein include full-bride load cells (FBLCs) and half-bridge load cells (HBLCs).
