Abstract
Current sense amplifiers with extended input common mode (CM) voltage range, including an extended CM input voltage amplifier that includes a low voltage (LV) p-type metal oxide semiconductor (PMOS) input module coupled to a positive supply rail, wherein said supply rail provides a voltage that is the maximum between a positive input signal (IN+) applied to the amplifier and an internal power supply voltage. The amplifier further includes a voltage regulator coupled to the supply rail that generates a decreased voltage level relative to the supply rail voltage that is provided to the LV PMOS input module via a high voltage ground (HV_GND) line. At least part of the LV PMOS input module is powered by a voltage difference between the positive supply rail and the HV_GND line. The voltage regulator maintains said voltage difference within an operating range of LV devices within the LV PMOS input module.
