Hi all,
I wonder if anybody know a software that can determine the parasitics on a PCB. That is, after drawing/routing a PCB, I want to find the capacitance of some sensitive traces to GND plan (or resistance between two points on a trace).
Thanx in advance
Hi DFF not necessary. Use a simple latch (two inverters + two switches as given in every digital design book) . Remember using non overlapping clocks for different latches.
Hi,
1. When Analog Input=0 then IN+=0 and In-=2.5V;
when in=2.5V then IN+=2.5V and IN-=0
So as in changes from 0 to 2.5V, (IN+ - IN- ) moves from -2.5V to 2.5V this is referred to as ±2.5v swing.
common mode level is the middle point on both of the inputs (each swing from 0 to 2.5) so it...
Hi,
here is what I know:
1. ADC (an ideal one) is by nature nonlinear. because its characteristic is stair case (obviosly it is not linear). This transfer characteriic generates harmonics and spurs.
2. Quantization noise is another expression for the above phenamena. Although it is modeled by...

Hi
1. Look in the following website; you can find RX and TX pins on the connector.
https://pinouts.ru/CellularPhones-P-W/erics_t28_pinout.shtml
2. another solution is to use the DATA CABLE of the phone set and connect it to you uC baord (which must have a TTL to RS232 converter as...
The type of tail curent varies among circuits for some circuits ou may need bandgap for other you may use constant gm biasing (see Razavi's book).
how ever I hope following two papers can help u.
the additional code (additional comparator) avoids the input of the next stage to be saturated (larger that |Vref| ) in presence of comparator offset. draw the characteristics for 1b and 1.5b stages!
May be its problem of the simulator (is it in high-accuracy mode?)
are the rise/fall tiems short enough?
when sampling fom a DC input is output accurate?
Filter design help
Depends on the type of the filter (active rc or switch-cap) also on the topology of filter.
For active-RC at least 100MHz is needed.( Even higher if low THD is needed).
