    摘要： According to embodiments of the subject matter disclosed in this application, a wide input common mode sense amplifier may include a level shifter stage and an amplifier stage. The level shifter comprises a CMOS differential amplifier that has a rail-to-rail input common mode range. The level shifter accepts two input signals with a common mode voltage in a rail-to-rail range and produces two output signals with a stable common mode voltage. The differential amplifier amplifies the two output signals from the level shifter stage with high gain. The disclosed sense amplifier may be used to measure delay between two discrete time events.

    摘要： A signal amplifier includes a pulse width modulator, a level shifter, and a power amplifier. The pulse width modulator is driven by a positive power supply and a negative power supply, and a reference voltage of the pulse width modulator is set to a GND. The power amplifier is driven by a positive power supply, and a reference voltage of the power amplifier is set to a middle value between the positive power supply and the GND. The level shifter shifts a voltage level of a first PWM signal whose high level corresponds to the positive power supply of the pulse width modulator and whose low level corresponds to the negative power supply of the pulse width modulator, to a voltage level of a second PWM signal whose high level corresponds to the positive power supply of the power amplifier and whose low level corresponds to the GND.
