Tool/software:
Hello there,
I'd like to know TMUX1208 CSON/CDON temperature data.
The value is 85pF @25deg. What about @ around 80deg ?
Thanks,
Murakami
Hi Murakami,
I'm looking into seeing if we have that data available for you. I'll update you by the end of the week.
Thanks,
Rami
Hi Murakami,
Really sorry about the delay. I wasn't able to find the data and was still digging around to no success.
Typically though the CON for an analog switch with a transition gate architecture will stay fairly constant across temp
Thanks,
Rami
Hi Rami,
This capacitance is composed of only gate oxide?
How is the source /drain bias dependence of the capacitance?
Thanks,
Murakami
Hi Murakami,
The capacitance is mostly gate oxide and also some metal capacitance. But you'll see your peak at VDD/2. In this architecture the NMOS and PMOS will both be turned on at VDD/2, adding extra capacitance. As opposed to when you're at either Vs = 0V or Vs = VDD where only one of the NMOS or PMOS are turned on.
Thanks,
Rami
