    Current and capacitor voltage calculation with IC in Razavi's book

    I started to read "Design of Analog CMOS Integrated Circuits", Second Edition, by Behzad Razavi and found this circuit in chapter 2 ("Basic MOS Device Physics") question 2.10a, page 40: I had a question regarding its transient response. It's described in detail here

    Steps in Designing using gm/ID Lookup table

    I am learning to design circuits using gm/ID lookup tables and I now try to design Miller OTA but I am no sure how to start. I have set myself parameters that I should strife to like: GBW, SR, CL. I first start with determining: \[ C_S = 0.22C_L \] \[ gm_{m12} =2\pi GBW C_L \] Here is my first...

    Designing a 0.18-µm CMOS Multi-Stage MOSFET Amplifier (150 V/V Gain, 1-5 GHz) Without External Resistors/Capacitors

    I'm working on a project to design a full-transistor-based (MOSFET) multi-stage amplifier using 0.18-µm CMOS technology. The requirements for the amplifier are as follows: Voltage gain of at least 150 V/V Input resistance less than 1 kilo ohm Upper 3-dB frequency (fH) between 1 GHz and 5 GHz...

    Demodulator design for differentially modulated signal.

    Hello, I am demodulating differential signal using LPF based demodulator. The schematics of the entire system is attached which include diff modulator, coupling capacitors, and demodulator. A modulated signal of 17 Mhz is demodulated. For the demodulator, I designed a 2-stage differential...

    Differential CBCM circuit with a voltage output and current-voltage mirrors

    I found this circuit below from a research paper and been trying to simulate it without success. The circuit is about measuring capacitance values of the Femto range. Please give your suggestion so that I will be able to measure the capacitance of a very small value.
