    Abstract: A level shifter circuit is described herein for shifting a signal from a first voltage domain to a second voltage domain. The level shifter circuit includes two current paths between a supply terminal of the first voltage domain and a supply terminal of the second voltage domain. The first and second current paths each include a differential transistor that receives a signal from a pulse generator in a first voltage domain. The pulse generator provides pulses to the differential transistors based on an input signal to be translated to the second voltage domain. The level shifter includes a latch circuit in the second voltage domain that includes two inputs where each input is biased at a node of one of the current paths. Each current path includes a bias transistor whose control terminal receives a compensated biasing voltage for biasing the bias transistor. The compensated biasing voltage is compensated to account for drive strength variation of at least one transistor in each current path.
