Both the above mentioned aspects of low frequency IC design are addressed in this work. Specifically, a family of OTA' s with very small transconductance has been designed using several design schemes such as current division, use of floating gate MOS and bulk driven transistors. A detailed comparison has been made among these schemes in terms of performance characteristics such as power consumption, active silicon area and signal to noise ratio. A multiplier based OTA with very small transconductance has also been designed with a view to obtain a wide transconductance tuning range. Moreover, an impedance scaling circuit has also been designed in order to realize very large capacitors on-chip. As sample applications for these circuits, a low pass filter, relaxation oscillator, band pass filter and a band pass based oscillator have also been designed, fabricated in a 1.2um analog process and successfully tested in the lab.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659527623\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783659527623","offer_id":39478706208861,"sku":"9783659527623","price":32.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/74e97a79-f613-4eeb-911c-ea7d5af027ed.jpg?v=1770097677","url":"https:\/\/shop.autorenwelt.de\/products\/continuous-time-analog-design-for-very-low-frequency-applications-von-anand-veeravalli-und-edgar-sanchez-sinencio","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
