Abstract: A sexual stimulating system with feedback control includes a physiological sensor, a sexual stimulator, and a processing module. The physiological sensor measures a physiological response of a user under sexual stimulation, and generates a sensor signal according to a result of the measurement of the physiological response. The sexual stimulator applies the sexual stimulation. The processing module is electrically connected to the physiological sensor and the sexual stimulator, receives the sensor signal, performs an analytical procedure upon the sensor signal for generating digital data, and generates a driving signal according to the digital data to control a degree of the sexual stimulation.

Abstract: A synthesis method of Sigma-Delta modulator capable of relaxing circuit specification and reducing power consumption, comprising the following steps: firstly, set a target bandwidth and a target performance; upon obtaining a Noise Transfer Function (NTF), perform coefficient synthesis a first time, to ascertain a plurality sets of first performance results corresponding to said NTF, and obtain a plurality sets of first circuit specifications fulfilling said target performance, through analyzing circuit non-ideal effect of said first performance results. Next, increase an oversampling ratio of parameters, to obtain a plurality sets of second performance results, and a plurality sets of second circuit specifications. Then, increase quantizer bit number, and increase attenuation quantity, to obtain a plurality sets of third circuit specifications. Finally, compare said first, second and third circuit specifications, to select one of greatest variation to perform calibrations.

Abstract: A method for synthesizing Sigma-Delta Modulator, which selects at least a system configuration and parameters, substitute a noise transfer formula into said system configuration to obtain coefficients. Using a least-square method to obtain a stability equation, and calculating an ideal performance of said system configuration based on said parameters and stability equation. Substitute the coefficients into non-ideal effect models, and acquire the circuit specification of an operation amplifier in said system configuration in a hierarchic approach to calculate the circuit performance of the operation amplifier. Determine whether said circuit specification of said operation amplifier has a solution based on related specification equation. If an answer is positive, calibrate length and width of transistors in said operation amplifier, until it meets the requirements of said circuit specification.
