Hibernating switched current cells for low power 14-bit Digital to Analog Converters
Static power dissipation remains an issue in low power, high speed and high resolution Digital to Analog Converters (DAC). The architecture of such converters often incorporate switched current sources for the higher significant bits of the input signal. In practice, a switched current source is com...

| description | Static power dissipation remains an issue in low power, high speed and high resolution Digital to Analog Converters (DAC). The architecture of such converters often incorporate switched current sources for the higher significant bits of the input signal. In practice, a switched current source is completely turned off when not contributing to generate the analog output and turned on when required. The energy required to reactivate the circuit contribute to static power dissipation. This work proposes a new type of hibernating switched current source that has lower reactivation energy, thus lowers static power dissipation. Simulation shows that the reactivation energy for a 14-bit, 100MHz DAC utilizing this new type of current cell is only 52.5 pJoules. This allows a low power dissipation of only 25mW. |
