Designing differential Signal modulator.

Thread Starter

I would like your suggestion on my first design Differential signal modulator [simulation attached].

Before jumping into design let me highlight my objective. I am differentiating a control signal of 1MHz and then modulating it with carrier frequency 15MHz(not limited to this specific value but for testing). The whole modulator needs to be integrated on a silicon substrate, in other words, the design should comply with IC design regulations i.e. occupy less space, power-efficient, and simple. The current design consumes 5.6mW power.

So I would request suggestions who had experience in a related field, that

1-How can I further improve this design?

2-Is there other alternatives design that would be much better than this one?

Your suggestions and comments will be highly appreciated. Thanks
