Systems and devices for ripple reduction in a DC/DC converter are presented. The disclosed systems and methods enable ripple reduction in discontinuous conduction mode (DCM) operation. In DCM, the inductor current peak to peak ripple may be reduced based on the load current. To achieve the reduction of the inductor peak to peak current ripple, a digital counter is used to count the time between consecutive PWM pulses. The digital output of the counter is used to control the pulse width ...

Disclosed are an angle modulator, a transmission apparatus, and a radio communication apparatus that can compensate phase discontinuity when an operational mode of a voltage controlled oscillator is switched. Angle modulator (100) includes phase difference detection section (150) that detects a difference of phases between an input signal of subtractor (141) and an angle modulated signal, using the result of subtraction by subtractor (141) of frequency locked loop ...
