Often resistors with large resistance values are implemented on chips by switches and capacitors as switched-capacitor resistors.

UGF vs. GBW in Op-Amps: Understanding Pole-Zero Doublets
The unity gain frequency (ωu) and the gain-Bandwidth product(GBW) are often considered as identical in ideal or standard circuit theory.
However, in real-world circuits, the unity gain frequency ωu is almost always slightly lower than the GBW.
MOSFET Noise Explained: Thermal & Flicker Noise Equations and Design Trade-offs
Noise is one of those things that every analog designer fights against sooner or later. It limits how small signals can be, reduces the SNR, and becomes especially painful in low-voltage and high-precision circuits.
What is the Body Effect in CMOS Transistors and How influences the Threshold Voltage Vth
The Body Effect is one of the 3 most important second-order effect of the MOSFET devices, together with channel-lenght modulation and subthreshold conduction.
Understand The Miller Multiplication Effect with easy Examples
The Miller transformation is a powerful technique for simplifying and analyzing of circuits by inspection.
Node Impedance of the MOSFET Terminals: Source, Drain and Gate
A MOSFET device exhibits different impedance characteristic when viewed from each of the 3 main terminals.
