Storage devices are capable of utilizing receiver devices with native devices configured to support lower voltage supplies for higher read performances. The receiver device may include a current source circuit, first and second stage circuits, and a duty cycle balancer circuit. The first stage circuit may utilize first and second native devices with a threshold voltage (VTH) that enables proper lower voltage operations in saturation at high speeds. The current source stage circuit may utilize a third native device to track a transconductance and provide a reference current that becomes proportional to VTH to maintain tighter gain across process, variation, and temperature (PVT). The second stage circuit may utilize a current folding stage to provide a high gain for faster conversion of intermediate signals. The duty cycle balancer may utilize a fourth native device to balance a rise and fall delay skew across the PVT to maintain tighter duty cycle.
