A frequency generation solution controls an oscillator amplitude using two feedback paths to generate high frequency signals with lower power consumption and lower noise. A first feedback path provides continuous control of the oscillator amplitude responsive to an amplitude detected at the oscillator output. A second feedback path provides discrete control of the amplitude regulating parameter(s) of the oscillator responsive to the detected oscillator amplitude. Because the second feedback path enables the adjustment of the amplitude regulating parameter(s), the second feedback path enables an amplifier in the first feedback path to operate at a reduced gain, and thus also at a reduced power and a reduced noise, without jeopardizing the performance of the oscillator. |

During battery manufacture cell components are exposed to water, and lithium silicate is water soluble. As lithium silicate dissolves, the pH of the water increases, which can etch silicon, degrading the anode active material. Such degradation can be mitigated by doping lithium silicate with multivalent elements or by converting some silicon to metal silicide before water processing. Doping of lithium silicate makes it less soluble in water. And metal silicide is not as easily etched as silicon. While retaining the excellent capacity and stability of silicon-oxide based material, these methods and the structures they produce have been shown to increase the effective energy density of batteries that employ such structures by offsetting capacity loss in the first cycles. |
