08 Dec 1989TL;DR: In this paper, a series resonant circuit for making resonant transfers of energy between the input capacitance of the power switching device and a storage capacitor is proposed to achieve substantially lossless gate switching.
Abstract: A high efficiency gate driver circuit for driving a power switching device of a high frequency converter includes a series resonant circuit for making resonant transfers of energy between the input capacitance of the power switching device and a storage capacitor to achieve substantially lossless gate switching. An ac switch couples the resonant circuit to the junction between upper and lower switching devices connected in a half-bridge configuration. The upper and lower switches of the half-bridge function to maintain the power switching device in either an ON-state or an OFF-state, respectively, depending on the transfer of energy being made. Timing circuitry ensures proper gating of the switching devices relative to operation of the ac switch.

01 Feb 1966TL;DR: In this article, an explicit expression for the output signal from an oscillator with several noise sources in the circuit is derived, which describes qualitatively and quantitatively the manner in which thermal and shot noise act to corrupt the performance of an ideal oscillator.
Abstract: An explicit expression for the output signal from an oscillator with several noise sources in the circuit is derived. This formula describes qualitatively and quantitatively the manner in which thermal and shot noise act to corrupt the performance of an ideal oscillator. The statistical properties of the signal are then evaluated, as it emerges from the oscillator stage, after passage through an output filter and after being operated on by an ideal n-times multiplier. Expressions are derived for the short term frequency stability, the power spectral density, and the power spectrum of the signal, as well as for the spectral density of the signal phase. The key to the results reported is an apparently novel perturbation technique which does not require smoothing of the instantaneous nonlinearity in the basic differential equation. Discussion of the solutions shows that the instantneous nonlinearities cause the device to act simultaneously like a linear AGC oscillator and like a high Q passive tuned circuit, with each aspect accorded one half the total noise excitation. Possible implications of this effect for other types of transient conditions in oscillators are indicated briefly.

TL;DR: In this paper, a solar cell receiver and an inductive device are coupled to form a resonant circuit having a selected resonant frequency associated therewith and being a function of the selected capacitance and the selected inductance, which resonates in response to a change in the signal to enable the solar cell to receive data carried by the signal.
Abstract: A receiver circuit and method for receiving a signal having a given carrier frequency. The circuit comprises: (1) a solar cell receiver having a selected capacitance and (2) an inductive device having a selected inductance and coupled to the solar cell receiver, the solar cell receiver and the inductive device cooperating to form a resonant circuit having a selected resonant frequency associated therewith and being a function of the selected capacitance and the selected inductance, the resonant circuit resonating in response to a change in the signal to thereby allow the solar cell to receive data carried by the signal. By employing solar cell as part of a resonant circuit, the range of optical remote controls can be extended to as much as a mile. In one embodiment, the receiver circuit forms a portion of a remote-controlled pool or spa.

TL;DR: A combination of IMPS and mNIRS can compensate for the glucose estimation error to improve its accuracy and an artificial neural network in external DSP is proposed to reduce the mean absolute relative difference.
Abstract: A multi-modal spectroscopy IC combining impedance spectroscopy (IMPS) and multi-wavelength near-infrared spectroscopy (mNIRS) is proposed for high precision non-invasive glucose level estimation. A combination of IMPS and mNIRS can compensate for the glucose estimation error to improve its accuracy. The IMPS circuit measures dielectric characteristics of the tissue using the RLC resonant frequency and the resonant impedance to estimate the glucose level. To accurately find resonant frequency, a 2-step frequency sweep sinusoidal oscillator (FSSO) is proposed: 1) 8-level coarse frequency switching (f STEP = 9.4 kHz) in 10–76 kHz, and 2) fine analog frequency sweep in the range of 18.9 kHz. During the frequency sweep, the adaptive gain control loop stabilizes the output voltage swing (400 mV p-p ). To improve accuracy of mNIRS, three wavelengths, 850 nm, 950 nm, and 1,300 nm, are used. For highly accurate glucose estimation, the measurement data of the IMPS and mNIRS are combined by an artificial neural network (ANN) in external DSP. The proposed ANN method reduces the mean absolute relative difference to 8.3% from 15% of IMPS, and 15–20% of mNIRS in 80–180 mg/dL blood glucose level. The proposed multi-modal spectroscopy IC occupies 12.5 mm 2 in a 0.18 µm 1P6M CMOS technology and dissipates a peak power of 38 mW with the maximum radiant emitting power of 12.1 mW.
