Abstract: A delta-sigma modulator includes a loop filter circuit having a first input that receives an input signal and a second input that receives a feedback signal. The loop filter circuit generates a filtered signal. A quantizer circuit quantizes the integrated signal to generate an output signal. An anti-windup circuit detects instances where the integrated signal is outside an input signal input of the quantizer circuit and in response thereto generates a dead zone signal having a magnitude and sign corresponding to a difference between the filtered signal and the input signal range. The feedback signal is a sum of the output signal and the dead zone signal.

Abstract: A method for preparing a sample for dynamic nuclear polarization which comprises submitting a solid substrate to a milling process in the presence of a polarizing agent at a temperature lower than the glass-transition temperature (Tg) of said substrate. Preferably said substrate may be in crystalline form.
