摘要： A method of trimming a current source in an IC includes deriving a reference voltage from an external supply, and developing a measurement voltage across an external reference resistance receiving the current to be trimmed. An on-chip ADC is used to provide corresponding digital reference and digital measurement signals. A digital comparator compares the digital signals and provides a digital trim signal, which is used to adjust the current to be trimmed until the digital measurement signal is equal to the digital reference signal within an acceptable tolerance. Gain and offset errors in the ADC cancel and do not affect the calibration of the trim operation.

摘要： Certain aspects of the present disclosure generally relate to automatic amplitude control of an oscillating signal output from a voltage-controlled oscillator (VCO) using feedback from an amplitude adjustment circuit. The VCO may comprise cross-coupled metal oxide semiconductor (MOS) transistors coupled to a resonant tank circuit. Gates of the cross-coupled transistors are configured to control an amplitude of the oscillating signal generated by the resonant tank circuit. In certain aspects, the amplitude adjustment circuit may comprise a peak detector that generates a signal that is representative of the amplitude of the oscillating signal. The signal generated by the peak detector may be compared to a reference voltage by an amplifier. The amplifier may generate a feedback signal to control the gates of the cross-coupled MOS transistors based on the comparison, thereby adjusting the amplitude of the oscillating signal.

摘要： A level shift circuit includes a level shift module and a voltage comparing module. The level shift module includes a plurality of stages of level shift units, each including a front-end circuit and an inverter circuit. The inverter circuit is electrically coupled to the front-end circuit and receives and inverts an output signal of the front-end circuit. The front-end circuit receives a clock signal, converts high/low voltage level of the clock signal into first/second voltage level, respectively, and outputs a respective signal with the first/second voltage level. The voltage comparing module is coupled to the level shift module and receives output signals of the inverter circuit of the first level shift unit and of the front-end circuit in the second level shift unit and compares the two output signals. The voltage comparing module outputs a short-circuit protection trigger signal when the two output signals have different voltages.
