  • Impedance measurement

    Sir/Madam, I have been designing a Differential drive rectiifer for UHF passive RFID in 130nm CMOS process. As the design of rectifier completes I got stuck with the impedance measurement, i.e. for finding input impedance of rectifier using Cadence Virtuoso. As it is a non-linear circuit which simulation...

  • Transient results as starting point in PSS

    Hello, Could we use the transient analysis results as a stabilization point (tstab) for PSS analysis? If so, how could we acheive it? Is there any documentation on this? Any inputs will be helpful. Prakash.

  • Issue with Envelope analysis

    Hi, I am simulating the I/Q upconversion using port through envelope analysis. The I input pwl file has samples of a cosine of frequency=5MHz and timestep=0.00125us. The Q input pwl file has samples of value=0 and timestep=0.00125us. The original I, Q pwl files have data upto 2ms. I have attached the...

  • modelling reflection in Cadence Virtuoso

    Hello Sir, I have been trying to design a UHF passive RFID tag in 130nm on Cadence Virtuoso IC 5.4.1. As for the design of a matching network between Antenna and Rectifier of RFID please tell me how reflections, if not matched, been modelled in Cadence Virtuoso. So whether I have to use any specifice...

  • STM065 536 Design Kit

    Hi, I am new with Cadence community I hope I get some help. I start to work on the STM065 536 design kit which support RFCMOS as well. I have a problems with the suitable model libraries that I should load in the ADE env in order to simulate some simple circuit, that for example has PMOS and NMOS of...

  • Have You Tried the New Transmission Line Library (rfTlineLib)?

    Happy New Year! Have you tried the new Transmission Line Library (rfTlineLib) yet? In case you missed it, rfTlineLib was introduced in IC 6.1.6 ISR1 plus MMSIM 12.1.1 -or- MMSIM13.1. You may wonder....Why should I use the new rfTlineLib ? Well.....here are a few reasons: Accurate and robust Consistent...
