Abstract: In an example, physiological signal(s) are received from physiological sensor(s) configured to measure at least one physiological property of a user. An arousal of at least one characteristic of at least one treatment resistant mood disorder is detected through employment of an estimation method based at least in part on at least one of the physiological signal(s). A value for at least one of a plurality of stimulation parameters is selected based at least in part on at least one of the physiological signal(s). An electric field based at least in part on the arousal is produced. The electric field is configured to stimulate at least a portion of a median nerve of the user transcutaneously. The electric field is based at least in part on at least some of the plurality of stimulation parameters.

Abstract: An embodiment of the invention is a method of generating a reduced bandwidth envelope signal VDD(t) for the power supply modulator of an RF amplifier. An envelope signal of an RF amplifier input Venv(t) is low pass filtered. The filtered envelope signal is subtracted from the envelope signal to obtain a difference signal, which is rectified to produce a residue signal. The residue signal is low pass filtered and added back into the filtered envelope signal. An iterative process of the rectifying, low pass filtering the residue signal adding it back is continued until a condition of VDD(t)?Venv(t) is met. Another embodiment provides a method of generating a reduced bandwidth envelope signal VDD(t) for the power supply modulator of an RF amplifier. An envelope signal of an RF amplifier input Venv(t) is low pass filtered. The filtered envelope signal is subtracted from the envelope signal to obtain a difference signal, which is rectified to produce a residue signal.

Abstract: A capacitorless DC-DC converter provides a controlled output voltage to a load, and includes a relatively wide bandwidth linear regulator placed in parallel with a switching regulator. Output signals from the linear regulator and switching regulator are added to form a combined output signal provided to the load. The switching regulator provides steady state current to the load, while the linear regulator provides higher-frequency transient current as needed. Because the linear regulator's transient response compensates for the limited transient response of the switching regulator, the substantial low-ESR output capacitance that is customarily required by conventional switching regulators is not needed. Further, feedback to the linear regulator taken from the combined output signal causes it to generate anti-phase ripple compensation, thereby reducing the magnitude of switching ripple in the converter's combined output signal.
