compare Spectre RF and @DS
i have experience in using both software for commercial product for Rf, below 20GHz, but above 2GHz.
my experience is that don't use spectre, it is totally useless, it is only toys.
i trust only hpads.
micromagic sue for windows
to be fully compatible with hspice, most of the spice version of schematic editor will do, but i recommend PSPICE. you can find freeware schematic also, but make sure they are spice compatible, and the netlist is editable.
eeprom circuit
i need to design a EEPROM circuit, these include:
1. control logic (read, write, etc);
2. charge pump to write;
3. interface circuit with other digital/analog part;
etc..., got not yet have solid idea what i actually need.
does any book describe this in detail, prefer can just...
DRC Rule Question
m2-m5 has to be wider as are build after the first CMP, while m1 is not, thus for higher yield m2-m5 is made wider. m6 normally is for current RFIC requirement. if only digital circuit, only m1-m4 is used for synthesis routing (m6 opt out for cost reason), m5 is then used to...
digital priciple and system design
start with flash first, maybe 4-bits, you need only resistor string, comparator, digital decision circuit.
pipeline is far complecated.
or, maybe you can start with ideal components simulation,
"CMOS Design, Simulation and Layout"
DRC Rule Question
for tsms or others foundry, metal width is decided by reliablity actually (resistivity, electrical etc. is fixed once the material is choosen), normally ten years for interconnect is required. m1, m2-m5, m6 has different thckness, thus, different width is required.
this is...
