Main MOSFETs

P channel

FDS9953A, digi-key FDS9953ACT-ND, max 2.9 A cont, typ 2.5/max 3.4 nC, <23 ns on/off time (fairchild package drawing)

N Channnel

SSM6N58NU, digi-key SSM6N58NULFCT-ND, max 4A continuous, 1.8nC gate charge, 29/9 ns on/off time, dual, EUR 0.34 (25 stuks)

MAX9012EUA+ digi-key MAX9012EUA+-ND: typ 20/30 mA short, prop delay 9ns, rise/fall 3 ns, 2.2 EUR (dual)
584-AD8564ARUZ-R, mouse, short current??? in tabel niet meer dan +/- 10 mA, in text 'can deliver up to 40 mA per channel'. Rest wel goed (en quad).
LMV7219M7, Farnell 1468946: typ 65 mA short, rise/fall time 1.3ns, prop delay typ 7, max 19 ns, EUR 2.96/stuk (1.6 voor 50)
NCX2200, farnell 2164804: typ 68 mA short, 10 ns transition time, ... 800ns prop delay...

N/P: DMG1029SV, digi-key, mouser: typ 0.3 nC, 15 ns, 6 Ohm, EUR 0.43
N/P: DMC2400UV-7, digikey, 0.5 nC, Vgs(th)=0.9V, 0.48 Ohm (Vgs=4.5V), EUR 0.25, SOT563
N/P: DMG1016UDW-7, digikey, typ 0.74 nC (740nC datasheet), Vgs(th)=1V , RdsON=0.5 Ohm (Vgs=4.5V), SOT363 (pitch 0.65)

Indactance calculator, or simpler, this one gives different/wrong? results

primary coil: length=110mm, diameter=11mm, N=100 => 9.7 uH,
- resistance: 100*3.14*10e-3/(3.14*.5e-3**2)*16.9e-9 = 68 mOhm
secondary coil: length=100mm, diameter=10mm, 1mm thick brass:
- inductance=8.0 uH/100^2=0.80nH (8.0uH is inductance for 10mm diameter coil)
- resistance: 65e-9 [Ohm m] * 3.14*5e-3 / (1e-3*100e-3) = 20 u Ohm
- L/R fall-off time: 0.8e-9/20e-6 = 40 us.
- resistance 'seen' on primary coil: 20e-6*100**2 = 0.2 Ohm.
secondary coil, stainless steel ([resistivity = 690 nOhm m, chemistry.about.com)
- resistance: 690e-9 * 3.14*10e-3 / (1e-3*110e-3) = 196 u Ohm
- L/R fall off time: 0.8e-9/ 217 u Ohm = 4.06 us
- resistance 'seen' on primary coil: 196 *100**2 = 1.96 Ohm, so with 200 primary turns, will be 7.9 Ohm.

L=\mu _{0}{\frac {N^{2}A}{l}}.

Load resistors: 15 ohm: 1623729-6, digikey, of 4.7 ohm [2] (both EUR 1.2)
LDO with Ceramic C's: ADP3338, LT1964-5 (digikey)
- 1.2V: MCP1700T-1202E/TT, digikey (stable with 1.2 uF ceramic C, EUR 0.4)
- 2.5V: MCP1700T-2502E/TT, digikey
- 3.3V: MCP1700T-3302E/TT, digikey
Coils (to measure current peaks/drops): 8nH, 2.3mOhm, 4A: AIAC-1512C-8N0K-T, digikey
Layouts: Solderrm-d

Add Lattice FPGA, for example ICE40LP384-SG32 digikey (heeft geen PLL!)
ICE40HX1K-VQ144 does have PLL (?) (HX variants seem to be the only ones with pins & PLL)
ICE40UL1K-SWG16ITR50 does have PLL (4x4 GBA, 0.35mm pitch, ...)
