Abstract: A method of operating a switched-mode power supply (SMPS) includes starting up the switched-mode power supply by determining a rate of increase of a duty cycle of a pulse width modulated (PWM) signal based on an input voltage and a switching frequency of the SMPS; and generating the PWM signal having the duty cycle in accordance with the determined rate of increase.

Abstract: Representative implementations of devices and techniques may minimize switching losses and voltage ripple in a switched capacitor de-de converter. A digital controller is used to control switching, based on an existing load. In some examples, the digital controller may insert a dead-time phase in a switching period, which may reduce voltage ripple for a low output load current. In other examples, the digital controller may adjust the conductance of a plurality of sub-switches, where the plurality of sub-switches may include one or more sub-switches that have a higher on-resistance than other sub-switches. For example, a sub-switch may have an on-resistance that is a multiple of the on-resistance of other sub-switches.

Abstract: Representative implementations of devices and techniques minimize switching losses in a switched capacitor dc-dc converter. The slope of the charging and/or discharging phase may be modified, smoothing the transitions from charge to discharge and/or discharge to charge of the switched capacitor.

Abstract: The disclosed polar modulation transmitter circuit is configured to generate an output signal having a transmission frequency that minimizes crosstalk effects between different transmission bands (e.g., Bluetooth, GSM, UMTS, etc.). In particular, a polar modulation transceiver circuit, having an amplitude modulated (AM) signal and a phase modulated (PM) signal, comprises a digitally controlled oscillator (DCO) configured to generate a DCO signal having a DCO frequency. The DCO signal is provided to one or more frequency dividers that are configured to selectively divide the DCO signal to generate various lower frequency signals, used to select a sampling rate for a DAC operating on the AM signal and an RF carrier signal frequency, which result in an output signal having a frequency that does not interfere with other RF systems on the same IC (e.g., that falls outside of the downlink frequency of other RF systems). Other systems and methods are also disclosed.
