Use chopper-stabilized amplifier as discrete chopper switch

Hello CVictor914,

all the switches have some charge injection when switching.
This will distort a low level signal.
Probably there is a better way to solve your problem.
Could you please provide details of your circuit?
What is the overall function? What is the purpose of that mixer?
What are your requirements regarding frequency, signal level, accuracy?

>> I just want to use one chopper switch in my design which seems like a mixer
Do you wat to built something like a ring modulator?
For this you will need a dual single-pole-dual-throw-switch with the smallest charge injection you can get.

>> ...could I use a chopper-stabilized amplifier to make a discrete chopper switch?
No.

Hi Alexxx,

Thank you for your reply.

I have found appropriate switches for my circuits. Like you said, it's a dual SPDT. 

Best regards,

Victor
