摘要： A fully differential amplifier slew rate boosting scheme for use with an amplifier having a closed-loop gain very near unity or less has the first plates of the compensation capacitors 50 and 52 conventionally coupled to internal high impedance gain nodes 40 and 42, but has the other plates of the compensation capacitors 50 and 52 unconventionally driven with the input signal IN+ and IN−. The voltages appearing across the compensation capacitors 50 and 52 in response to changes in the input signal is significantly less than that achieved using conventional compensation architectures where the other plates of the compensation capacitors are coupled to ground. Since little current is now required to charge the compensation capacitors 50 and 52, the input stage tail current no longer limits the slew rate.

摘要： A track-and-hold circuit is provided. This track-and-hold circuit is adapted to track an analog input signal and hold a sampled voltage of the analog input signal at a sampling instant for processing by other circuitry, in response to a track signal that alternates with a hold signal. Preferably, the track-and-hold circuit includes a bi-directional current source that sources and sinks current through a first output node and a second output node, a unity gain amplifier that is coupled to first and second output nodes of the bi-directional current source and that receives the analog input signal, a resistor coupled to an output of the unity gain amplifier, and a capacitor coupled between the resistor and ground. Of interest, however, is the bi-directional current source, which includes a differential input circuit that is adapted to receive the track signal and the hold signal and that is coupled to the first and second output nodes and an RC network that is coupled to the differential input circuit. The RC network receives the analog input signal and is scaled to change the location of a zero to reduce the signal-dependence of the sampling instant.

摘要： Accelerometers have a number of wide-ranging uses, and it is desirable to both increase their accuracy while decreasing size. Here, millimeter or sub-millimeter wavelength accelerometers are provided which has the advantage of having the high accuracy of an optical accelerometer, while being compact. Additionally, because millimeter or sub-millimeter wavelength signals are employed, cumbersome and awkward on-chip optical devices and bulky optical mediums can be avoided.

摘要： Traditionally, pipelined continuous-time (CT) sigma-delta modulators (SDM) have been difficult to build due at least in part to the difficulties in calibrating the pipeline. Here, however, a pipelined CT SDM is provided that has an architecture that is conducing to being calibrated. Namely, the system includes a digital filter and other features that can be adjusted to account for input imbalance errors and well as quantization leakage noise.

摘要： A track-and-hold or sample-and-hold (S/H) circuit for an analog-to-digital converter (ADC) is provided. A difference between the disclosed S/H circuit and conventional S/H circuits is the use of a peaking circuit. This peaking circuit generally provides increased current to switching transistor when transitioning between track and hold which can increase the Spurious-Free Dynamic Range (SFDR) as low frequencies, by as much as 15dB.
