摘要： A method for generating a reference voltage in an integrated circuit device that is powered by a low voltage power includes generating a coarse first reference voltage using a coarse reference generator, routing the coarse first reference voltage to a boost regulator as an input reference voltage by a hand-off switch circuit, the boost regulator generating an initial-state stepped-up supply based on the first reference voltage, and generating at least two outputs of a second, more accurate, reference voltage from the stepped-up supply voltage using a fine-resolution reference generator. The second reference can be then looped back to the boost regulator, thus, generating a more accurate steady-state stepped-up supply voltage.

摘要： A driver circuit includes first switch, configured to selectively couple a first driving node to a power supply node, and a second switch, configured to selectively couple a second driving node to a ground node. The first driving node is coupled to each transistor in a first set of PMOS transistor(s) and the second driving node is coupled to each transistor in a second set of NMOS transistor(s). The driver circuit is configured to propagate a first drive signal in a first direction along an electrical path for biasing the first and second sets of transistors when the transistors in the first set, before receiving the first drive signal, are in a first state. The driver circuit is configured to propagate a second drive signal in a second direction along the path when the transistors in the first set, before receiving the second drive signal, are in a second state.

摘要： A noise shaper that compares an input signal to a feedback output signal, which is a truncated version of the input signal, and generates the difference between the two signals (i.e., the error). The noise shaper then integrates the errors by adding to the error multiple of its delayed versions, and quantizes the integrated errors in such a way that the spectrum of the quantization noise is shaped toward high frequencies to be removed by a LC low-pass filter used in conjunction with the noise shaper. The low frequency content of the desired signal is mostly unaffected.
