Abstract:
A voltage modulator using only switched capacitors is presented. Depending on the desired output voltage a combination of capacitances is connected to the output capacitance, to increase or decrease the output voltage. The circuit is capable of delivering output signals within a frequency range from DC up to 100 kHz, with all harmonic distortion components below 30 dB. Operating at a supply voltage of 1.8 V, it delivers a maximum output power of 32mW with an efficiency of 72%.
