Abstract: An amplifier includes a differential positive input, a differential negative input, and a transistor. The transistor is communicatively coupled to the differential positive input and differential negative input at a source of the transistor. The transistor is configured to track input common mode of the differential positive input and differential negative input.

Abstract: A high side current sensing amplifier architecture is simplified and improved over prior art current sensing amplifier circuits by using chopping only, without requiring auto-zeroing, and by using a simpler (and faster) switched capacitor filter instead of an auto-zeroing integrator filter. Also, VIP (positive DC sense node) is merged with the VDDHV (power supply) node, such that the integrated circuit package requires only a single node (package pin) to accommodate both the VIP and VDDHV connections for the current sensing amplifier circuit, resulting in being able to use a smaller integrated circuit package. A small resistor is coupled between VIP and VDDHV to reduce the offset considerably. A low latency time high voltage level shifter is provided which is essential for precise chopping operation.
