the total current noise have a pole at $\omega_\mathit{eff}$, and thus the signal-to-noise (which is equivalent to rereferencing to TES power) remains flat all the way up to $\omega_{S/N \, \delta \! P_{t}}$.

Unfortunately, neither the squid noise $$S_{P_{t} SQUID}=\frac{1}{\frac{\partial I_{t}}{\partial P_{t}}} S_{I_{t} SQUID}
\label{eq:Spt-squid}$$ nor the Johnson noise from the load resistor, R$_{l}$, $$S_{P_{t} \, R_{l}}  \! = \frac{4 k_{b} T_{to} R_{to} (1 + \beta)^{2}}{(R_{l} \! + \! R_{o}\left[1\! + \! \beta\right])^{2}} \! 
                \left( \frac{1}{\frac{\partial \! I_{t}}{\partial \! P_{t}}}+\! I_{to}R_{to}(2 \! + \! \beta) \right)^{2}
\label{eq:Spt-Rl}$$ can be trivially written in terms of $G_{tb}$. However, as shown in Fig. \[fig:Spt-Sit\] they are subdominant to the combination of $G_{tb}$ TFN and $R_{t}$ Johnson noise (this latter can also be seen through comparison of Eq. \[eq:Spt-Rl\] to Eq. \[eq:Spt-Rt\]).

Finally, we would ideally like to have an estimate of the $1/f$ noise found in the current CRESST experimental setup, particularly since there are some indications that it could be an important contributor to the overall noise in CRESST currently [@Emilija_2008_thesis]. More importantly, we would like to estimate the 1/$f$ noise expected in a next-generation experimental setup to assess its effect on the device design. For the former, significant effort would be
