Hi there,
I have a project to design a 4th-order source follower lowpass filter for medical applications. Here are the specifications:
I am using Cadence Virtuoso to design and simulate the circuit. I am designing the internal circuit of the opamp using NMOS and PMOS transistors. So I use the biquad design and it doesn't seem to be working. I need help in whether the biquad design is suitable or there is other better circuit design. Thanks a lot!
I have a project to design a 4th-order source follower lowpass filter for medical applications. Here are the specifications:
- Supply Voltage: 2.5V
- Filter order: 4th-Order
- Cutoff Frequency: 3kHz, 5kHz, 8kHz, 10kHz programmable
- Power Consumption: <2mW
- Design Tech: 0.35um CMOS
