The variation of absolute data-to-output delays [T.sub.DQ,min] with FF input capacitance ([C.sub.in]) for 16X (19.92 fF) capacitive load is illustrated in Figure 14.
The measured frequency was 1.06 MHz, the input capacitance [C.sub.in] = 6 pF, the power dissipation capacitance [C.sub.pd] = 12 pF and the load capacitance was 47 pF, except the equivalent capacitance of the frequency measurement node, which has approximately 51 pF.
Unlike a typical 10:1 high-impedance scope probe with a 10-pf input capacitance, a transmission-line probe's much smaller capacitance doesn't begin to degrade input impedance until very high frequencies are reached.
The gate input capacitance [C.sub.iss] (when bulk shorts to source) does not originate solely from the gate-source capacitance [C.sub.gs] (and the gate-drain capacitance [C.sub.gd]).
Assuming the transistor model shown previously, the energy required to charge the input capacitance [C.sub.GS] from the threshold voltage [V.sub.TH] ([V.sub.TH] = 0 for this model) up to the minimum input voltage for device switching [V.sub.SW] is
This calculation begins by determining the ratio between detector capacitance [C.sub.D] and transistor input capacitance [C.sub.in] that results in minimum noise.
Their high DC input impedance of 1 MQ and the low input capacitance (0.6 pF) ensure that the load on the DUT's operating point remains low.
An input capacitance of 4.0 pF (0201 package) and 4.5 pF (0402 package).
The devices are capable of attenuating unwanted signals by more than 30 dB over the 900 MHz up to 2.3 GHz frequency range, with a resistance of 100[ohm] and an input capacitance of 60 pF.
Here, a transistor with a small input capacitance is required.
The proposed memcapacitor emulator is designed in the way of composing the input capacitance as a function of applied voltage.
