I'm using a 130nm process, from the diagram I can see that lambda it's not constant, so in order to choose the lenght values i must have this kind of diagram for my process?
Also I've tried to simulate the circuit, but i can't get the three p-MOS to get in the saturation region, they always...
Hi, I am designing a CMOS differential amplifier for a course, I must obtain a gain of 20 dB and a cutoff frequency of 100 MHz.
This is the circuit
I got my transfer function, and from there my gain is given by , i can see that it's given in terms of the transconductance which i can obtain...
I'm using a generic class.
My endpoint is Toggle type.
And i send a character say "a" from PC1 and then i receive it in PC2 but when i send another character from the PC1, the PC2 receives an "í".
Hi, i'm trying to send and receive data from one pc to another via USB, i'm using two PIC's 18F4550 and VC++.
The problem is that it only works once in each pic, what i mean is that i can send from pc and receive in the other one, and do the same in the other PC, but after this i only receive...
I used USBDeview to see all the information on the USB devices recognized in my computer, but even when it recognize the PIC the serial number still doesn't appear.
And i was thinking since in the Device Descriptor is the USB_DEVICE_DESC[] defined, maybe in the PIC program i could get that it...
Yes I know that in the code it says something about the serial number, but the problem is that the driver mchpusb doesn't support it. How can I access the serial number?? Is there a VC++ function for this?
This is the header i use to declare the Class in VC++
// USB.h: interface for the USB class.

#if !defined(AFX_USB_H__801FD7DD_554C_4197_A9AF_6A4FC934E5FA__INCLUDED_)

I'm using a special header (that was provided at class) for the compiling for the PIC. Here i found the device descriptor part you mentioned. But i'm not really sure what to modify.

Hi, I've managed to connect the PIC18F4550 via USB and the PC recognized it, the problem is that i need to connect a second one, but where do i tell the PC is a different PIC?.
I know that i can't use the serial number option due to the limitations of the microchip driver.
I'm using Visual C++...
Hi!! I'm trying to initialize an LCD 16x2 JHD162A, i'm doing it through Visual C++ 6 and the parallel port, but the problem is that it only responds to the first command that indicates the 8 bit interface, i'm using the following diagram:
