These values are based on the gain curve below and the requirement that the time scale of the ripple be less than 50ps. Converting to voltage from picoseconds can be done using a linear approximation of the rising edge of a typical pulse (300mV peak height, ~2ns rise time). The spec for the 10Hz-20MHz range is set by the gain curve peak around 80kHz.+ − + + Line 71:

==== Final Production v2 ====
Due to some DAC channels in the v1 set of boards not working properly and thus eliminating our set of spares, the control board has been remade. There were also changes to the physical v1 boards after fabrication that have been included in the schematics and pcb drawings in v2.

=== Power Supply Requirements ===
We require the following voltages on the boards:
# +100V (range 80V - 100V) for biasing
#*1V steps from 80V - 100V
#*typical operation at 85V
#*maximum current demand 500mA (50W power)
#*maximum ripple P-P 50mV @ f < 1kHz
#*maximum noise P-P 5mV @ 1kHz < f < 5MHz
#*maximum HF noise P-P 20mV @ f > 5MHz
#*long-term variation < ±50mV (0.05%)
# +6V (range 5.5V - 6.0V) for preamplifier VCC;
#*0.01V steps from 5.5V to 6.0V
#*typical operation at 5.75V
#*maximum current 8A (50W power)
#*maximum ripple P-P 10mV @ f < 1kHz
#*maximum noise P-P 5mV @ 1kHz < f < 5MHz
#*maximum HF noise P-P 20mV @ f > 5MHz
#*long-term variation < ±10 mV
# +5V for cmos logic VCC
#*fixed 4.95V - 5.05V, no adjustment required
#*maximum current 3A (15W power)
# -5V for DAC
#*fixed -4.95V - (-5.05V), no adjustment required
#*maximum current 65mA (0.325W power)
The ripple specs for the 100V and the 6V power supplies are based on the two coupling curves shown below, for coupling from Vbias (top plot) and preamp VCC (bottom plot) into the output signal. The Vbias curve was computed assuming R18=100Ohms.

=== Power Supply Requirements ===
===Power Supply Design from Fernando B.===
I recommend the following implementation for the TAGM supply system:
# One (1) MPOD-MINI - Wiener MPOD chassis, 5U high, 4 slots
# One (1) MPV8008LI - LV for preamps, logic (+5V, +6V)
# One (1) MPV8120I - Bias supplies for SiPMs (+100V).
Each of these supplies has 8 channels and we will use 6 from each. We will design a distribution box with inputs from the above supplies and 6 outputs; 6 cable assemblies will provide the proper supply levels to the 6 backplanes of the TAGM.
The power required for each of these channels is as follows:
The above supplies meet or exceed your spec requirements on the wiki. Please review [http://www.wiener-d.com/sc/power-supplies/mpod--lvhv/mpod-mini-crate.html the supply specs here] and [http://www.wiener-d.com/sc/power-supplies/mpod--lvhv/mpod-lv-module.html here]
These implementation will cost less than $15k (chassis, modules, distribution boxes, cables, etc) and it is fully compatible, including controls, with the remaining systems in Hall D. Also note that there is a 12 week lead time so decision is urgent.
